Successful laparoscopic resection for giant mature cystic teratoma of the pancreas: a case report and surgical refinements

BackgroundMature cystic teratomas or dermoid cysts of the pancreas complicate surgical approaches because of their anatomical position and ever-growing size. Herein, we report a case of a giant mature cystic teratoma of the pancreas that was successfully resected via complete laparoscopic distal pancreatectomy (LDP).Case presentationA 39-year-old female patient was referred to our hospital for the evaluation of a pancreatic tumor. Three years of follow-up revealed that the tumor had increased in size to 18 cm, with hyperintense solid components on diffusion-weighted magnetic resonance imaging. Considering the possibility of malignancy, we decided to perform an LDP. The capsule appeared solid enough to withstand the retraction of the endoscopic forceps. Tumor size made it difficult to dissect the dorsal side of the tumor from the caudal to the cranial side. Early transection of the pancreas and additional ports facilitated dissection of the dorsal side of the tumor. We completed the LDP without intraoperative cyst rupture. On pathological examination, the tumor was diagnosed as a mature cystic teratoma originating from the pancreatic tail. The patient was discharged on postoperative day 13 with no complications.ConclusionLDP may be an option for surgical procedures in patients with large cystic lesions of the pancreatic body or tail. Intraoperative observation of the tumor and surgical refinement are necessary to complete the laparoscopic procedure without tumor rupture.

Abstract PO1-20-08: Primary breast implant-associated squamous cell carcinoma with subsequent TEMPUS testing and failure of immunotherapy

Abstract Primary squamous cell carcinoma of the breast is a rare entity, and there are a limited number of cases in the literature describing squamous cell carcinoma arising from breast implants. It has been hypothesized that these implant-associated cancers may arise from epithelialization of the implant capsule followed by chronic inflammation. None of the cases in the literature were treated with immunotherapy. We present a case of an aggressive, primary sarcomatoid squamous cell carcinoma of the breast arising from a breast implant that was treated unsuccessfully with simultaneous chemotherapy and immunotherapy following TEMPUS testing. Introduction: Breast augmentation is the most common plastic surgery procedure performed worldwide, with more than 300,000 done in the United States every year. While breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is extensively discussed in recent literature, other breast implant-associated cancers are rarer and less studied. Breast implant-associated squamous cell carcinoma (BIA-SCC) specifically is an extremely rare complication of breast augmentation and no guidelines for treatment exist. The American Society of Plastic Surgeons (ASPS) released a statement on BIA-SCC on 9/2022 following a safety communication from the FDA, and it is recommended health care providers submit case reports of BIA-SCC to a patient registry. Case study: We present the case of a female patient who underwent bilateral breast augmentation in 2006 with Mcghan textured, pre-pectoral, areolar saline implants. In 2022, she presented with swelling and a lump in her breast and underwent bilateral breast implant removal with capsulectomy. Pathology showed triple negative sarcomatoid squamous cell carcinoma of the right breast capsule. TEMPUS testing on the breast biopsy revealed a PIK3CA mutation and PD-L1 negative status. Her case was discussed with a multi-disciplinary team including plastic surgery, multiple oncologists, and radiation oncology and her clinical picture was determined to be most consistent with BIA-SCC. Based on the KEYNOTE-522 study, she was determined to be a candidate for neoadjuvant therapy with pembrolizumab and chemotherapy as she was newly diagnosed, previously untreated, nonmetastatic, and had a triple negative tumor. She received two cycles of carboplatin, paclitaxel, and pembrolizumab but unfortunately rapidly progressed with chest wall extension, multiple new pulmonary nodules, worsening lymphadenopathy, right ventricular tumor thrombus, and new malignant pleural effusion and was transitioned to hospice. Discussion: Seven cases of BIA-SCC, one case of squamous cell carcinoma (SCC) after liquid silicone injection augmentation, one case of squamous metaplasia on the breast implant capsule, and one case of epithelization of the breast implant capsule have been previously described in the literature (Table 1). None of the available cases of BIA-SCC report TEMPUS testing, and none of the patients were treated with immunotherapy. The origin of BIA-SCC is unclear, but several theories have been described including chronic inflammation leading to conversion of epithelial tissue on the capsule to SCC. It is unknown how the breast implant capsule might become epithelialized to begin with – introduction of epithelium intraoperatively during augmentation, rupture of epidermal cysts, existence of epithelium in the area from a childhood injury or from birth, or epithelization from chronic shear forces from the augmentation or leakage of the implant are all possibilities. With the ongoing data gathering through the FDA patient registry, we will continue to learn more about these rare cancers and potentially get further insight into their origins.

An alternative surgical technique for removal of multiple uveal cysts in a dog: A case report.

Uveal cysts have been reported to cause vision changes in dogs. The objective of this article is to report removing multiple uveal cysts from both eyes of a canine patient using a previously unreported methodology. A bimanual irrigation and aspiration procedure is reported here as an alternative method for managing multiple anterior segment iris cysts in the dog. The results of the surgery were mild postoperative inflammation that resolved within 1 week and no other complications were encountered. Overall, the authors conclude that the procedure was a less invasive alternative to the traditional approaches for removal of multiple uveal cysts including laser rupture of cysts, direct aspiration or removal using coaxial irrigation and aspiration through a standard clear corneal approach to the anterior chamber with or without the aid of viscoelastic floatation. The procedure eliminated the need for sutures, marked activity restrictions, or an Elizabethan collar postoperatively. This is the first report of bimanual irrigation and aspiration for multiple uveal cyst removal in dogs.

Changes in anti-Müllerian hormone values for ovarian reserve after minimally invasive benign ovarian cystectomy: comparison of the Da Vinci robotic systems (Xi and SP) and the laparoscopic system.

To investigate the impact on the ovarian reserve after minimally invasive ovarian cystectomy using two platforms, the Da Vinci robotic system (Xi and SP) and the laparoscopic system. Patients underwent laparoscopic or Da Vinci robotic (Xi or SP) ovarian cystectomy for benign ovarian cysts between January 1, 2018, and December 31, 2022 at Guro Hospital, Korea University Medical center. We measured the change of AMH values (%) = [(postAMH - preAMH)] × 100/preAMH. No significant differences in preoperative age, cyst size, estimated blood loss during surgery, hemoglobin drop, length of hospital stay, adhesion detachment rate and cyst rupture rate were observed. However, the operative time was significantly shorter in the laparoscopic group than that in the robotic group (67.78 ± 30.58 min vs. 105.17 ± 38.87min, p < 0.001) The mean preAMH and postAMH were significantly higher with the Da Vinci robotic group than with the laparoscopic group (preAMH: 5.89 ± 4.81 ng/mL vs. 4.01 ± 3.59ng/mL, p = 0.02, postAMH: 4.36 ± 3.31ng/mL vs. 3.08 ± 2.60ng/mL, p = 0.02). However, the mean ΔAMH was not significantly different between two groups. ΔAMH also did not demonstrate significant differences among the three groups; laparoscopic, Xi and SP robotic. Even in the patient groups with preAMH < 2 and diagnosed with endometriosis, the ΔAMH did not show significant differences between the laparoscopic and robotic groups. The Da Vinci robotic system is no inferior to conventional laparoscopic systems in preserving ovarian function.

Clinical characteristics and surgical outcomes of transcutaneous versus transconjunctival excision of Wolfring gland ductal cysts.

To analyze the clinicopathological characteristics and surgical outcomes of patients with Wolfring gland ductal cysts (WGDCs). A retrospective, consecutive, interventional comparative case series was performed over a period of 7 years. Data on demographic and clinical characteristics, pathological findings and outcomes of surgically excised cysts were collected. A comparison between the transconjunctival and transcutaneous approaches was also assessed. Forty-eight patients (48 eyelids) were included in the final analysis. The most common presenting symptom was painless eyelid swelling (81.3%). The median symptom duration was 11.5 months (IQR, 18.25). The upper eyelid was involved in 31 (64.6%) patients, 29/31 of whom had cysts in a medial or centromedial location. Forty-five (93.8%) cysts were bluish gray and transilluminable with clear contents on lid eversion and a median largest dimension of 22mm (IQR, 8). A transverse conjunctival fibrotic band was observed along the proximal tarsal border in the cyst area in all patients. Signs of chronic trachoma were noted in 38 (79.2%) patients. Preoperative significant ptosis was present in 28/31 (90.3%) of the upper eyelid cysts. Thirty cysts (62.5%) were excised through the skin, and 18 cysts (37.5%) were excised transconjunctivally. Intraoperative cyst rupture, the need for conjunctival grafting and postoperative residual upper lid ptosis were significantly greater in the transconjunctival group (p = 0.009, p < 0.001, and p = 0.016, respectively). The present study highlights the clinicopathological characteristics of a relatively large series of surgically excised WGDCs. Transcutaneous excision of WGDCs has proven to be an effective treatment with fewer adverse sequelae than the transconjunctival approach.

Optic Nerve Edema in Pediatric Middle Cranial Fossa Arachnoid Cysts: Report of 51 Cases from a Single Institution

BackgroundMiddle fossa arachnoid cysts (MFACs) are rare, congenital lesions that may rupture and cause symptoms of elevated intracranial pressure (ICP). Thus, we sought to describe the presence and factors associated with optic nerve edema in MFACs, focusing on the utility of ophthalmologic evaluations for guiding cyst management. MethodsWe reviewed clinical and radiographic information for all MFAC patients with ophthalmologic evaluations at our institution. Headache, cranial nerve palsy, emesis, altered mental status, fatigue, and seizures were considered MFAC-related symptoms. Univariate and multivariable analyses evaluated factors associated with optic edema. ResultsFifty-one patients between 2003-2022 met inclusion. Most patients were symptomatic with a single arachnoid cyst. Cysts were a median volume of 169.9 cm3 (IQR: 70.5, 647.7). Evidence of rupture with subdural hematoma/hygroma occurred in 19 (37.3%) cases. Eighteen (35.3%) patients underwent surgery for their cyst and/or rupture-associated intracranial bleed.Eleven (21.6%) patients had optic edema; all were symptomatic and experienced cyst rupture. Ten of these patients received surgery. Postoperatively, optic edema resolved in 80% of cases. Cyst volume and symptoms were not associated with optic edema, however, patients with ruptured cysts, particularly those with traumatic rupture, were more likely to have optic edema and receive surgery (p<0.001). ConclusionsWe found optic edema in 21.6% of evaluated MFACs, this comprised of 57.9% of ruptured cases. Optic edemawas not found in unruptured cysts. Cyst fenestration improved optic edema and patient symptoms. In conjunction with clinical history and neuroimaging, optic edema may help guide MFAC management, particularly in patients with cyst rupture.

Traumatic Rupture of Dermoid Cyst in Early Pregnancy: Diagnosis and Management in Peki Government Hospital Resulting in a Successful Delivery at Term

Introduction: Dermoid cyst is the commonest germ cell tumour, constituting about 20% of adult ovarian tumours. They are mostly asymptomatic, but complications such as torsion, rupture, and malignant transformation have been reported. Only a few cases of ruptured mature cystic teratoma in early pregnancy have been described and even fewer are those in early pregnancy with the pregnancy successfully carried to term with successful delivery. Case Presentation: We present a case of a grand multiparous woman who presented to Peki Government Hospital at 11 weeks gestation with an acute abdomen following a fall. She had been diagnosed with a dermoid cyst a week with dimensions of 20cm x15 cm before the presentation. Ultrasound diagnosis of a possible rupture of the cyst was made on admission. Right oophorectomy was done at laparotomy. She had progesterone support for the succeeding 4 weeks and the pregnancy was successfully carried to term with good outcomes at delivery for both mother and baby. The APGAR score for the baby at 1minute and 5minute after birth were 7/10 and 8/10 respectively. Conclusion: Traumatic rupture of dermoid cyst should be considered as a differential diagnosis in women presenting with acute abdomen in early pregnancy. Laparotomy with abdominal lavage is a viable management option in a low-resource setting.

Structural Characterization of Toxoplasma gondii Brain Cysts in a Model of Reactivated Toxoplasmosis Using Computational Image Analysis

Toxoplasma gondii is an obligate intracellular parasite existing in three infectious life stages—tachyzoites, bradyzoites, and sporozoites. Rupture of tissue cysts and re-conversion of bradyzoites to tachyzoites leads to reactivated toxoplasmosis (RT) in an immunocompromised host. The aim of this study was to apply ImageJ software for analysis of T. gondii brain cysts obtained from a newly established in vivo model of RT. Mice chronically infected with T. gondii (BGD1 and BGD26 strains) were treated with cyclophosphamide and hydrocortisone (experimental group—EG) or left untreated as infection controls (ICs). RT in mice was confirmed by qPCR (PCR+); mice remaining chronically infected were PCR−. A total of 90 images of cysts were analyzed for fractal dimension (FD), lacunarity (L), diameter (D), circularity (C), and packing density (PD). Circularity was significantly higher in PCR+ compared to IC mice (p &lt; 0.05 for BGD1, p &lt; 0.001 for the BGD26 strain). A significant negative correlation between D and PD was observed only in IC for the BGD1 strain (ρ = −0.384, p = 0.048), while fractal parameters were stable. Significantly higher D, C, and PD and lower lacunarity, L, were noticed in the BGD1 compared to the more aggressive BGD26 strain. In conclusion, these results demonstrate the complexity of structural alterations of T. gondii cysts in an immunocompromised host and emphasize the application potential of ImageJ in the experimental models of toxoplasmosis.

A Troublesome Complication of Hydatid Cysts; Intra-Abdominal Rupture: A 10-Year Study from a High-Volume Center.

Hydatid cyst is a parasitic infection, often caused by Echinococcus granulosus. Although it is classified as a benign disease, cyst ruptures in the abdomen can be fatal. Ruptures occur spontaneously or after trauma. We aimed to report data from patients who underwent emergency surgery due to spontaneous intra-abdominal hydatid cyst rupture. Upon a retrospective review of the records at Department of General Surgery, Faculty of Medicine, Harran University, Şanlıurfa, Turkey, we found that 34 cases were operated on due to hydatid cyst rupture between January 2012 and October 2022. All patients were operated on in an emergency, and partial cystectomy, intra-abdominal irrigation, and drainage were performed using laparotomy. The patients were evaluated in terms of age, sex, symptoms, radiological findings, laboratory results, intraoperative findings, and postoperative follow-ups. Twenty-two (64.7%) female and 12 (35.3%) male patients were enrolled. The mean age was 39.1 (±17.58) years. All patients experienced spontaneous rupture. The ruptured cyst was found in the liver in 32 patients (94%), the spleen in 1 patient (3%), and the pelvis in 1 patient (3%). The diagnosis was determined using ultrasonography in 12 (35.3%) patients, computed tomography in 21 (61.8%) patients, and magnetic resonance imaging in 1 (2.9%) patient. All patients exhibited acute abdomen and leukocytosis. The average length of hospital stay was 5.14 (±1.37) days. Hydatid cyst rupture should be considered in cases of acute abdomen, particularly in regions where the disease is endemic, as in our region. The ruptured hydatid cyst was primarily observed in the liver (94.11% of cases).

The Impact of Pulmonary Hydatid Cyst Rupture on COVID-19 Symptom Severity.

Co-infection with other microorganisms such as parasites in patients with COVID-19 can affect the clinical outcome and require prompt diagnosis and appropriate therapy. We present a case of an adult male with chest pain, dyspnea, cough, diplopia, and anorexia who was confirmed to have acute COVID-19 pneumonia. 2weeks prior to admission, a hydatid lung cyst was identified on examination, but the patient refused surgery. Thoracoabdominal computed tomography (CT) revealed a rupture of the lung hydatid cyst and co-infection with COVID-19. The patient has prescribed a treatment protocol for COVID-19 and albendazole. Despite measures taken to manage severe inflammation and decreasing blood oxygen levels, the patient required admission to the intensive care unit (ICU) and intubation. After approximately 3weeks of hospitalization, the patient was successfully extubated and discharged uneventfully from the hospital. Oral albendazole was prescribed for follow-up treatment. Our case highlights the importance of considering hydatid cysts in the differential diagnosis of patients with COVID-19, especially those living in endemic areas.

Validation of ADNEX and IOTA two-step strategy and estimation of risk of complications during follow-up of adnexal masses in low-risk population.

The aim is to evaluate the ability of the Assessment of Different NEoplasias in the adneXa model (ADNEX) and the International Ovarian Tumour Analysis (IOTA) two-step strategy to predict malignancy in adnexal masses detected in an outpatient low-risk setting, and to estimate the risk of complications in masses with benign ultrasound morphology managed with clinical and ultrasound follow-up. This single center (Hospital Universitari Dexeus Barcelona) study was performed using interim data of the ongoing prospective observational IOTA phase 5 study. The primary aim of the IOTA 5 study is to describe the cumulative incidence of complications during follow-up of adnexal masses classified as benign on ultrasound. Consecutive patients with adnexal masses detected between June 2012 and September 2016 in a private center offering screening for gynecological cancers were included and followed-up until February 2020. Tumors were classified as benign or malignant based on histology (if patients underwent surgery) or outcome of clinical and ultrasound follow-up at 12 (±2) months. Multiple imputation was used when follow-up information was uncertain. The ability of the ADNEX model without CA125 and of the IOTA two-step strategy to distinguish benign from malignant masses was evaluated retrospectively using the prospectively collected data. We describe performance as discrimination (area under the receiver operating characteristic curve, AUC), calibration, classification (sensitivity and specificity) and clinical utility (Net Benefit). In the group of patients with a benign looking mass selected for conservative management we evaluated the occurrence of spontaneous resolution or any mass complication during the first 5 years of follow-up by assessing the cumulative incidence for malignancy, torsion, cyst rupture, or minor mass complications (inflammation, infection, or adhesions) and the time to occurrence of an event. A total of 2654 patients were recruited to the study. After application of exclusion criteria, 2039 patients with a newly detected mass were included for the model validation. 1684 (82.6%) masses were benign, 49 (2.4%) masses were malignant and for 306 (15.0%) masses the outcome was uncertain and imputed. The AUC was 0.95 (95% CI 0.89-0.98) for ADNEX and 0.94 (95% CI 0.88-0.97) for the two-step strategy. Calibration performance could not be meaningfully interpreted due to few malignancies resulting in very wide confidence intervals. The two-step strategy had better clinical utility than ADNEX at malignancy risk thresholds < 3%. 1472 (72%) patients had a mass judged to be benign based on pattern recognition by an experienced ultrasound examiner and were managed with clinical and ultrasound follow-up. In this group, the 5-year cumulative incidence was 66% for spontaneous resolution of the mass (95% CI 63-69), 0% for torsion (95%CI 0-0.002), 0.1% for cyst rupture (<0.1-0.6), 0.2% for a borderline tumor (<0.1-0.6), and 0.2% (0.1-0.6) for invasive malignancy. The ADNEX model and IOTA two-step strategy performed well to distinguish benign from malignant adnexal masses detected in a low-risk population. Conservative management is safe for masses with benign ultrasound appearance in such a population. This article is protected by copyright. All rights reserved.

Laparoscopic Management of Abdominal Echinococcosis: A Technical Report on Surgical Techniques and Outcomes.

This technical report explores the efficacy and methodology of laparoscopic surgery for treating abdominal echinococcosis, a parasitic infection caused by Echinococcus granulosus. We highlight the zoonotic nature of the disease, which predominantly affects the liver and occasionally other organs, noting the challenge of its asymptomatic progression that complicates timely diagnosis and intervention. We detail our surgical technique using a standard laparoscopy kit to address abdominal hydatid cysts, emphasizing the critical importance of preventing cyst rupture and spillage to avoid recurrence and anaphylactic shock. We discuss considerations for opting for laparoscopy over open surgery, such as reduced postoperative morbidity, faster patient recovery, and lower costs, while also acknowledging limitations like restricted instrument movement and the absence of haptic feedback. We advocate hypertonic saline as the preferred scolicidal agent and strategies to minimize spillage and manage the residual cavity. In conclusion, we assert that laparoscopy offers a viable and effective treatment option for abdominal echinococcosis, emphasizing that optimizing outcomes for this benign condition hinges on careful patient selection and a conservative surgical approach.

Specialized Laparoscopic Devices in the Treatment of Hydatic Hepatic Cysts: A Retrospective Analysis and Review of the Literature.

Background and objective While hydatid disease is associated with a high prevalence only in certain endemic areas, it can be encountered in any geographical region. The characteristics of this parasitic disease, and its implications during development, such as the risk of seeding, and the complications caused by cyst rupture, means that its therapeutic management should adhere to strict principles and may sometimes require approaches specially tailed for this type of pathology. In this study, we aimed to provide a comparative analysis of conventional laparoscopic techniques vs. treatment withspecialized instrumentation in these patients. Methods Our study involveda retrospective evaluationof a cohort comprising 41 patients diagnosed with hepatic hydatid cysts, who underwent procedures with both conventional laparoscopic techniques and specialized instrumentation tailored for this particular pathology. Furthermore, we conducted a comprehensive review of the literature examining alternative types of laparoscopic instrumentation specifically crafted for the management of hydatid cysts. This review employed an extensive search utilizing PubMed and Google Scholar databases. Results The examination of cases within our study revealed a high prevalence of hydatid disease among male patients (63.41%) and a predominance of instances originating from rural regions necessitating emergent admissions (p<0.05). Notably, in 58.54% of cases, surgical interventions employed specialized instrumentation, with a notable discrepancy in conversion rates to open surgery favoring the standard approach: 12.2% vs. 2.44% (p=0.025). Additionally, the laparoscopic approach was associated with prolonged surgical durations compared to the dedicated technique (p=0.002), besides a higher incidence of postoperative complications (12.2% vs 7.32%). Furthermore, patients undergoing laparoscopic procedures with standard instrumentation experienced lengthier hospital stays (p=0.002). Our comprehensive review of the literature identified six distinct surgical methodologies utilizing specifically tailored instrumentation for addressing hydatid cysts. Analysis of these findings underscored a preference for single localizations and selective cases. Postoperative complication rates ranged from 6.66% to 22.22%, with conversion rates to open surgery reaching up to 23.33%, and recurrence rates observed to be as high as 7.81%. Conclusions The patented approach, which uses special trocars that provide stable anchorage and allow a safe puncture-aspiration, reaspiration, and fragmentation processes, has superior characteristics compared to the laparoscopic approach with standard instrumentation. Comparative analysis with other similar procedures described in the literature has shown similar results regarding the frequency of complications, with our technique being superior in terms of approaching multiple cysts and recurrence rate. It has been successfully applied even in unselected cases.

Presentation, diagnosis, management and outcome of complicated hydatid cyst of the lung

Introduction: Introduction: The complicated hydatid cyst of the lung is defined as any cyst ruptured in the bronchi tree or in the pleural cavity, infected, and rarely in the pericardial cavity. The aim of this study was to evaluate the problems of complicated pulmonary hydatid cyst, including presentation, diagnosis choice of surgical methods. and complication of delay in surgical treatment of pulmonary hydatid cysts. Methods: Between 2016 and 2021, 192 operations operated for pulmonary hydatid cysts, 42 of these patients were complicated hydatid cyst. Presentations were cough, chest pain and dyspnea.Diagnosis tools were CXR and CT-scan of chest. surgical approach was a posterolateral thoracotomy and anterolateral thoracotomyin all patients; a phrenotomy in eight patients and one-stage bilateral thoracotomy in six patients. Results: In 18 patients (67.5%), there were single hydatid cysts; whereas 4 patients (32.5%) had multiple cysts.12 patients had bilateral cyst and 8 had both lung and liver and others organs, 6 patients had preoperative hydatid cyst history. Iatrogenic rupture of an intact hydatid cyst occurred in 4 patients. Extrathoracic involvement was apparent in 6 patients (27%). Intrathoracic but extrapulmonary involvement was apparent in 4 patients (16%). Conclusion: Complicated hydatid cyst may present with different clinical and radiologically manifestations as a primary lung tumor , pleural effusion ,empyema hydropneumothorax. In patients with suspicious lung masses in endemic area or history of a hydatid cyst in patients a complicated pulmonary hydatid cyst may be in differential diagnosis.

Post-Traumatic Rupture of a Pleural Hydatid Cyst: A Case Report

Introduction:The preferred site of the hydatid cyst is the liver followed by the lung [1]. The extrapulmonary intrathoracic locations are usually the mediastinum, pleura, pericardium and chest wall. Most reported cases of intrapleural hydatid cysts are secondary; the primary pleural location is rare [2]. Case presentation: We report the case of a 16-year-old girl, operated two years ago for a pulmonary hydatid cyst, admitted to the emergency room in acute respiratory distress in the aftermath of a minimal trauma, responsible for the rupture of a pleural hydatid cyst in the pleural cavity. Discussion: A primary pleural hydatidosis ruptured in the pleural cavity was retained by a thoracic scan. Despite its rarity, our case raises the suspicion of primary pleural hydatidosis in the presence of a large pleural cyst and small daughter vesicles floating in the pleural cavity with deviation of the mediastinal structures and pleural effusion.

Images in Gastrointestinal Infection: Endoscopic Management of Intrabiliary Rupture of the Hydatid Cyst

Images in Gastrointestinal Infection: Endoscopic Management of Intrabiliary Rupture of the Hydatid Cyst

A rare case in emergency department: intracranial dermoid cyst rupture

Intracranial dermoid cysts (IDC) are rare cystic lesions that are present from birth. After rupture of these cysts, patients may present to the hospital with ischemic cerebral symptoms, headaches, seizures, syncope, and meningitis. Brain magnetic resonance imaging (MRI) is the most sensitive radiologic method in the diagnosis of IDC rupture, which has a high mortality rate. Patients should be rapidly evaluated for surgery if a symptomatic and ruptured cyst is detected. In this presentation, we aimed to describe the diagnosis and treatment of IDC in a 23-year-old male patient brought to the emergency department after syncope.

Corpus luteal cyst rupture presenting as massive spontaneous hemoperitoneum in women with dengue infection: A case series

Corpus luteal cyst rupture presents with acute pain abdomen, hemoperitoneum and features of shock. The condition clinically closely mimics acute rupture ectopic pregnancy but has negative urine pregnancy test. Massive hemoperitoneum requires urgent surgical exploration and achievement of hemostasis. Here is a case series describing 3 cases of corpus luteal cyst rupture in patients with diagnosed dengue fever presenting with features of acute abdomen with or without shock at emergency. All were managed surgically, did well in postoperative period, had transfusions of blood and blood products and finally discharged in satisfactory condition. The objective of this series is to highlight the importance of this condition as a differential diagnosis in patients with acute abdomen which is not much described in medical literature.

A Comprehensive Analysis of Potential Complications after OLIF : A Review of Postoperative Magnetic Resonance Scans in Over 400 Cases.

This study focuses on identifying potential complications following oblique lumbar interbody fusion (OLIF) through routine magnetic resonance (MR) scans. From 650 patients who underwent OLIF from April 2018 to April 2022, this study included those with MR scans taken one-week post-operatively, and only for indirect decompression patients. The analysis evaluated postoperative MR images for hematoma, cage insertion angles, and indirect decompression efficiency. Patient demographics, post-operatively symptoms, and complications were also evaluated. Out of 401 patients enrolled, most underwent 1- or 2-level OLIF. Common findings included approach site hematoma (65.3%) and contralateral psoas hematoma (19%). The caudal level OLIF was related with less orthogonality and deep insertion of cage. Incomplete indirect decompression occurred in 4.66% of cases but did not require additional surgery. Rare but symptomatic complications included remnant disc rupture (4 cases, 1%) and synovial cyst rupture (4 cases, 1%). This study has identified potential complications associated with OLIF, including approach site hematoma, contralateral psoas hematoma, cage malposition risk at caudal levels, and radiologically insufficient indirect decompression. Additionally, it highlights rare, yet symptomatic complications such as remnant disc rupture and synovial cyst rupture. These findings contribute insights into the relatively under-explored area of OLIF complications.

Transdiaphragmatic rupture of hydatid cyst: A rare case report

Hydatid disease is a major zoonotic disease worldwide. It remains a serious health problem in developing countries and in countries where animal husbandry is common. Here, we report the case of a 40-year-old male who presented with chief complaints of pain in the right upper quadrant of the abdomen and swelling of the right side lower chest for 2 days. He mentioned intermittent episodes of pain within the past 7 days, the frequency and severity of which is increasing in the past 2 days. Chest X-ray suggestive of opacity of the right lower hemithorax with blunting of cardiophrenic angle seems like pleural effusion with opacity in the right upper lobe but on ultrasound, cystic area with multiple septations found in right lung parenchyma likely suggestive of hydatid cyst.
