Granulomatous mastitis forming a well-defined large mass diagnosed by surgical excision: a case report

BackgroundGranulomatous mastitis is a relatively rare benign inflammatory disease of the breast, but it is sometimes difficult to distinguish from breast cancer by imaging. We experienced a case that was definitively diagnosed as granulomatous mastitis from the surgical specimen. The mass appeared as a large cystic lesion on imaging, which is unusual for granulomatous mastitis, and was initially suspected to be an encapsulated papillary carcinoma.Case presentationA 43-year-old woman presented with a painful mass in her right breast. Ultrasonography revealed a cystic mass lesion with internal solid components, with partially indistinct cyst walls and abundant blood flow. Additionally, lymphadenopathy of one axillary lymph node was observed. Magnetic resonance imaging findings showed irregularly spreading enhanced nodules within the cystic lesion, raising the suspicion of encapsulated papillary carcinoma. Although the histological findings from a needle biopsy were consistent with granulomatous mastitis, the possibility of malignancy could not be ruled out based on imaging, prompting a diagnostic probe lumpectomy. However, the surgical specimens did not reveal any tumorous lesions, and we reached a final diagnosis of granulomatous mastitis. Postoperatively, the patient was followed-up without steroid therapy and has been free from recurrence of mastitis for 22 months after surgery.ConclusionsWe report a case of granulomatous mastitis that was detected as a large cystic lesion with a well-defined border on imaging and a definitive diagnosis was made from a surgical specimen.

Analysis of ultrasound and magnetic resonance imaging characteristics of kaposiform hemangioen dothelioma

ObjectiveThe present study aims to investigate the ultrasound and magnetic resonance imaging (MRI) characteristics of kaposiform hemangioen dothelioma (KHE).MethodsA retrospective analysis was conducted on the clinical data of children diagnosed with KHE through postoperative pathology. Patients were divided into two groups: the KHE group and the KHE with Kasabach-Merritt Phenomenon (KMP) group (KMP group). Laboratory indicators, ultrasound, and MRI data were collected and analyzed statistically to summarize the imaging characteristics of the disease.ResultsThe levels of platelets and fibrinogen in the KHE group were significantly higher than those in the KMP group, while D-dimer levels, prothrombin time, and activated partial thromboplastin time were lower (P < 0.05). Ultrasound characteristics comparison revealed that lesions extending to the fat layer (42.47% vs. 54.24%) and invading the muscle layer (38.36% vs. 69.49%) were less common in the KHE group compared to the KMP group, with the lesion diameter being smaller in the KHE group (P < 0.05). The Adler grading predominantly showed Grade II (45.21%) in the KHE group, whereas Grade III (93.22%) was more prevalent in the KMP group (P < 0.05). MRI analysis indicated that the incidence of lesions invading the muscle layer and the presence of flow voids were lower in the KHE group compared to the KMP group (P < 0.05).ConclusionKHE patients with KMP exhibit lesions that are more prone to extending into the fat layer and invading the muscle layer, with larger diameters and abundant blood flow. Additionally, the MRI images of the lesions may exhibit flow voids.

The Management of Splenic Injuries.

Splenic injury is one of the most common abdominal parenchymal organ injuries. Since the spleen is a parenchymal organ with abundant blood flow, its injury can easily result in hemorrhagic shock. Therefore, prompt and appropriate management for hemostasis is critical. Management of splenic injury is determined by the hemodynamic status and the grade of injury. Splenectomy is the primary choice in cases with unstable hemodynamics, but splenic repair or non-operative management, including conservative treatment or transcatheter arterial embolization (TAE), may be chosen to preserve the spleen if time permits. Non-operative management has advantages over operative management in terms of complications and medical economics. TAE also plays a significant role in non-operative management by contributing to the improvement of patient outcomes.

Cartilage Homeostasis under Physioxia.

Articular cartilage receives nutrients and oxygen from the synovial fluid to maintain homeostasis. However, compared to tissues with abundant blood flow, articular cartilage is exposed to a hypoxic environment (i.e., physioxia) and has an enhanced hypoxic stress response. Hypoxia-inducible factors (HIFs) play a pivotal role in this physioxic environment. In normoxic conditions, HIFs are downregulated, whereas in physioxic conditions, they are upregulated. The HIF-α family comprises three members: HIF-1α, HIF-2α, and HIF-3α. Each member has a distinct function in articular cartilage. In osteoarthritis, which is primarily caused by degeneration of articular cartilage, HIF-1α is upregulated in chondrocytes and is believed to protect articular cartilage by acting anabolically on it. Conversely, in contrast to HIF-1α, HIF-2α exerts a catabolic influence on articular cartilage. It may therefore be possible to develop a new treatment for OA by controlling the expression of HIF-1α and HIF-2α with drugs or by altering the oxygen environment in the joints.

A rare case of concomitant endometrioid adenocarcinoma arising from uterine adenomyosis and clear cell carcinoma arising from parametrial deep endometriosis

BackgroundCarcinomatous changes from the ectopic endometrial glands in endometriosis have been reported in many studies, but malignant transformation from uterine adenomyosis/adenomyoma is rare. And clear cell-like adenocarcinoma represents a seldom-encountered malignant pathological variant of ectopic endometrium.Case presentationThis case report presents a case of a 44-year-old nulliparous woman begun with abdominal pain and intestinal obstruction. Past medical history showed laparoscopic ovarian endometriotic cyst excision. Ultrasound indicated adenomyoma and a parametrial hypoechoic nodule with abundant blood flow signals and unclear boundaries. Deep invasive endometriosis was considered preoperatively. The patient underwent laparoscopic subtotal hysterectomy and bilateral adnexa resection. Chocolate cyst-like lesion was observed in the parametral lesion. Postoperative pathological examinations suggested endometrioid adenocarcinoma arising from eutopic endometrium and adenomyoma. Ectopic endometrium in the myometrium combined with atypical hyperplasia and formation of endometrioid adenocarcinoma. Left parametrial lesions suggested poorly differentiated endometrioid adenocarcinoma combined with clear cell carcinoma. CD10 + endometrial stromal cells were observed surrounding tumor cell masses. Combined with surgical founding and pathological characters of the left parametrial adenocarcinoma, the parametrial lesions were more likely to be carcinomatous changes of the original deep endometriosis.The patient underwent subsequent transabdominal tumor cell reduction surgery and chemotherapy.ConclusionWe herein present a rare case of combined endometrioid adenocarcinoma arising from uterine adenomyosis and clear cell carcinoma arising from parametrial deep endometriosis that may help inspire additional studies in the future. The patient underwent robot-assisted laparoscopic subtotal hysterectomy, bilateral adnexa resection, deep endometriosis lesion resection and bilateral ureteral stent placement. Following surgery, a chemotherapy regimen of Taxol and Carboplatin was administered.

Analysis on the ultrasonic characteristics of tonsillar lymphoma

Objective: To analyze the ultrasonic features of tonsillar lymphoma to improve the diagnostic accuracy. Methods: The clinical, pathological and ultrasonic data of nine patients with tonsillar lymphoma confirmed by pathology at Tianjin Medical University Cancer Institute and Hospital during June 2015 and June 2022 were analyzed retrospectively, and the characteristics of their ultrasonic images were summarized. Results: All 9 cases of tonsil lymphoma were unilateral tonsil disease, including 4 cases on the left side and 5 cases on the right side. The average maximum diameter of tonsil lymphoma in 9 cases was 4.32 cm. There were 3 cases with simultaneous involvement of tonsil and cervical lymph nodes, all of which were ipsilateral lymph nodes. Gray scale ultrasound showed that the lesions were hypoechoic, with clear boundaries in 7 cases and unclear boundaries in 2 cases. The shape was full and irregular in 5 cases and oval in 4 cases. The echo was uniform in 7 cases and uneven in 2 cases. Color Doppler ultrasonography showed abundant internal blood flow signal in 1 case, a little dotted linear internal blood flow signal in 5 cases, and no obvious internal blood flow signal in 3 cases. Conclusions: The ultrasonic features of tonsillar lymphoma include hypoechoic area, clear boundary, full shape, irregular and uniform internal echo, no or low linear signal of internal blood flow. Ultrasonography is of great value in the diagnosis of this disease and can help clinical decision-making.

Non-mass-type ductal carcinoma in situ of the breast on ultrasound: Features and pathological analysis.

The aims of this study were to investigate the ultrasound features of non-mass-type ductal carcinoma in situ (DCIS) of the breast and conduct a pathological analysis. Ultrasound images of 32 cases of non-mass-type DCIS of the breast, collected between September 2014 and June 2016, were analyzed. The characteristics of the lesions, including border, internal echogenicity, local glandular hyperplasia, micro-calcification, and intra-tumoral blood flow resistance index (RI), were analyzed, and a concurrent pathological analysis was conducted. Obvious local glandular hyperplasia was commonly observed in the 32 cases of non-mass-type DCIS of the breast. The internal echogenicity varied in intensity, exhibiting a "leopard pattern" or "zebra pattern." Color Doppler imaging revealed abundant blood flow signals within the lesion with an RI of >0.7. Isolated duct dilatation and micro-calcifications were occasionally observed within the lesions. High-grade DCIS was the predominant pathological type of non-mass-type DCIS. Non-mass-type DCIS of the breast often presents with obvious local glandular hyperplasia and varying internal echogenicity. High-grade DCIS is the frequent pathological type. Color Doppler imaging and RI measurement can assist in diagnosing non-mass-type DCIS of the breast.

Prenatal diagnosis of fetal intracranial medulloepithelioma: a case report

Intracranial medulloepithelioma is a very rare and highly malignant tumor that is typically diagnosed in childhood and has an inferior prognosis. In the current report, we described a case of fetal intracranial medulloepithelioma that was detected during the third trimester by prenatal ultrasonography, which displayed homogenous echogenicity with well-circumscribed margins and abundant blood flow. On magnetic resonance imaging, it was hyperintense on both T1- and T2-weighted magnetic resonance imaging. The fetal intracranial tumor was progressive, with rapid expansion within 3 weeks. The report aimed to provide knowledge on the clinical characteristics of fetal intracranial medulloepithelioma in prenatal diagnosis, particularly the radiological features.

Contrast-enhanced ultrasound for rare testicular tuberculosis

Testicular tuberculosis is a rare form of genital tuberculosis. Ultrasound is a crucial tool for evaluating male genital disorders. Contrast-enhanced ultrasonography (CEUS), which provides real-time monitoring of microvascular hemodynamics, provides rich information about microcirculation, helping distinguish testicular tuberculosis from other testicular conditions such as tumors and inflammation. This study reports on a rare case of testicular tuberculosis diagnosed through CEUS. A 31-year-old male patient presented with two months of persistent right scrotal pain and swelling. Conventional scrotal ultrasound showed an enlarged right testicle with heterogeneous echogenicity and abundant color Doppler blood flow signals. CEUS demonstrated rapid contrast agent filling in the right testicle, followed by the appearance of several irregular regions, indicating perfusion deficits in these areas. Histopathological confirmation through ultrasound-guided biopsy revealed granulomatous inflammation with caseous necrosis, which is consistent with the diagnosis of testicular tuberculosis. As a real-time monitoring technique for microvascular hemodynamics, CEUS provides valuable microcirculatory information that enhances diagnostic accuracy and enables the formulation of appropriate treatment plans for testicular tuberculosis versus other testicular pathologies.

SURG-43. SURGICAL TREATMENT FOR SPINAL CORD HEMANGIOBLASTOMA - DIFFERENCE IN SURGICAL INDICATION FROM CEREBRAL HEMANGIOBLASTOMA

Abstract Objective Spinal cord hemangioblastoma (HB) is a tumor with abundant blood flow with feeders and drainers, and is often accompanied by large cysts and syringomyelia. About 25% of HB cases are said to be von Hippel-Lindau (VHL) disease cases, which is a hereditary tumor disease. In VHL disease, multiple surgeries are often performed because HB occurs frequently. To consider whether spinal cord HB requires a different surgical indication from brain HB cases, this report analyzed the treatment results of HB cases at our hospital. Methods From 1988 to 2021, 85 patients with HB underwent surgery at our hospital investigated. Results There were16 cases of spinal cord, 58 of cerebellum, and 10 of brainstem. Of these, 46 cases (13 families, 21 patients) had VHL disease. There were 13 cases (81%) with syringomyelia and 8 cases (50%) with cysts in spinal cord HB. The mean tumor volume at spinal cord, cerebellum and brainstem were 3.2, 15.9 and 5.8 cm3, respectively. Changes in mRS before and after surgery were as follows; spinal cord HB: improvement 10 (63%)/deterioration 3 (19%), cerebellar HB: improvement 35 (60%)/deterioration 7 (12%), brainstem HB: improvement 7. (70%)/0 deterioration. In spinal cord HB, total resection was achieved in all cases, and no significant complication was observed. Conversely, 12 patients (17%) underwent shunting for postoperative hydrocephalus in cerebellum/brain stem HB. In spinal cord HB, no local recurrence was observed during the follow-up period of median 54 months (4-188 months). Conclusion Spinal cord HB was operated when the tumor volume was smaller than that of brain HB, but there was no significant difference in the symptom improvement rate. However, there were a certain number of patients who deteriorated after surgery, and it was thought that further analysis would be necessary in the future regarding appropriate surgical indications for spinal cord HB.

Ultrasound diagnosis of the small intestinal adenomyoma in children.

Adenomyoma is an exceptionally rare hamartoma in the small intestine. Few data have been reported on the featuresof this rare disease. The aim of this study was to describe the ultrasound (US) characteristics of small intestinal adenomyomas.Material and methods: This retrospective study analyzed the clinical features and US data of 15 pediatric patients diagnosedas small intestinal adenomyomas in the age range between 1 day to 12 years in our hospital during 2014-2021. Theclinical manifestations of all the small intestinal adenomyomas were abdominal pain, vomiting or/and hemafecia. The smallintestinal adenomyoma usually acted as the lead point of secondary intussusception. They were identified in the ileum (n=11),jejunum (n=2), and Meckel's diverticulum (n=2). The diagnostic accuracy (the concordance rate between US diagnosis andpathological diagnosis) of small intestinal adenomyoma was 73.3%. The small intestinal adenomyoma had approximately1.0-3.0 cm, were typically located in the submucosal region, had the basal part wide and without a pedicle, and its boundarieswere clear. The mass protruded into the intestinal cavity, and showed oval hypoechoic polycystic echo nodules, containingmultiple small quasi-circular or irregular cysts of different sizes surrounded by solid hypoechoic mosaic areas. The colorDoppler US showed in the solid hypoechoic areas of the mass abundant or sparse blood flow signals.Conclusions The USfindings of small intestinal adenomyomas in children are characteristic, and US is valuable in the identification of intestinaladenomyomas in children.

Ultrasound diagnosis and treatment of branchial cleft cyst and preoperative management.

The ultrasonic diagnosis of cervical and facial cystic masses, as well as cases of missed diagnosis and misdiagnosis, was examined, to improve the diagnosis of branchial cleft anomalies. A retrospective analysis was conducted on 17 patients with branchial cleft cyst anomalies, including 11 males and 6 females, aged 12-53years, with an average age of 33 ± 2years, were unilateral single. All patients who underwent an ultrasound examination and image storage for retrospective analysis, and both longitudinal and transverse sections were scanned to observe the shape, size, boundary, peripheral relationship, and blood flow signal of the masses. All cases were examined with an enhanced CT scan, and pathological reports were generated. Among the 17 cases of branchial cleft anomalies, 15 cases were branchial cleft cysts, while one case involved fistula formation and one case involved sinus tract formation. Based on the type of branchial cleft, the first, second, and third cysts were classified in 4, 12, and 1 case, respectively. The sensitivity rate and specificity of ultrasonic diagnosis were 14/17 (82.4%) and 4/6 (66.7%), respectively. Ultrasonic characteristic analysis for the masses can be found in simple cystic masses or hypoechoic masses, most of them are of a regular shape and have a distinct boundary, and almost no blood flow signal. All patients who were misdiagnosed exhibited blood flow signals, including 1 patient with an abundant blood flow signal, 1 patient suspected of having ectopic thyroid with an abnormal function due to the rat-tail sign, 2 patients misdiagnosed as local inflammatory focus, and 1 patient misdiagnosed with tuberculous lymphadenitis. Ultrasound has a detection rate of up to 100% for cervical and facial masses, providing a fundamental determination of lesion characteristics and specific guidance for preoperative diagnosis. If the blood flow signals can be identified and carefully considered their peripheral relationship, the diagnostic rate can be improved.

Ultrasonographic Characteristics in the Fingers and Other Superficial Glomus Tumours.

Glomus tumours are painful superficial tumours, and ultrasonography is an extremely useful and noninvasive diagnostic technique for superficial organs. In this study, we retrospectively examined glomus tumours using ultrasonography. Among 18 patients histopathologically diagnosed with glomus tumours via ultrasonography, we observed five different development sites: subungual areas or those surrounding the nail bed (12), other areas on the finger surface (3), abdominal wall (1), upper arm (1), and forearm (1). The ultrasonographic images revealed significant differences in tumour size, indicating that tumours on other body surfaces tended to be smaller than those on patients' fingers (p < 0.01). The depth/width ratios of tumours on the other body surfaces were significantly higher than those on the fingers (p < 0.05). The tumours showed a regular shape (72.2%) and clear border (100%). Furthermore, most tumours were low-echo tumours with a diameter of up to 15 mm, clear margins, and no lateral shadows. Abundant blood flow and vessels in and out of the tumours were also observed. In conclusion, our study describes the ultrasonographic characteristics of glomus tumours and reveals that they cannot be ruled out when diagnosing small painful subcutaneous tumours.

Analysis of risk factors for patients with cesarean scar pregnancy treated with methotrexate combined with suction curettage.

To analyze the predictive value of clinical and ultrasound parameters for treatment failure after administration of methotrexate (MTX) in combination with suction curettage (SC) in treatment of cesarean scar pregnancy (CSP) in the early first trimester. In this retrospective cohort study, electronic medical records of patients diagnosed with CSP and initially treated between 2015 and 2022 with MTX combined with SC were reviewed and outcome data were collected. 127 patients met inclusion criteria. 25 (19.69%) required additional treatment. Logistic regression analysis indicated that factors independently associated with the need for additional treatment included progesterone level > 25mIU/mL (OR: 1.97; 95% CI: 0.98-2.87, P = 0.039), abundant blood flow (OR: 5.19; 95% CI: 2.44-16.31, P = 0.011), gestational sac size > 3cm (OR: 2.54; 95% CI: 1.12-6.87, P = 0.029), and the myometrial thickness between the bladder and gestational sac < 2.5mm (OR: 3.48; 95% CI: 1.91-6.98, P = 0.015). Our study identified several factors which increase the need for additional treatment following the initial treatment of CSP with MTX and SC. Alternative therapy should be considered if these factors are present.

Clinical and imaging features of Kaposiform hemangioendothelioma in infants

ObjectiveKaposiform hemangioendothelioma (KHE) is a locally aggressive tumor of vascular origin. This study investigated the clinical and imaging features of KHE to provide a reference for its early diagnosis. MethodsThe clinical and imaging findings of 27 clinically confirmed KHE cases (including 21 with focal lesions and 6 with diffuse lesions) between January 2016 and December 2021 were retrospectively analyzed. ResultsThe mean age of the 27 patients was 105 ± 80.27 days. Twenty-two (81.5%) of these patients had Kasabach–Merritt phenomenon. Most KHEs were located in the trunk and/or extremities (22/27). Ultrasonography showed heterogeneous echogenicity and/or striated hypoechoic bands with abundant or patchy blood flow within the tumor. On plain computed tomography (CT), they appeared as heterogeneous lesions isodense with the muscles, with a CT value of 29.58 ± 11.53 HU. In the arterial phase, the KHEs showed striated or lamellar heterogeneous enhancement, with a CT value of 153.91 ± 52.11 HU after enhancement. All KHEs showed uneven and high signal intensity on T2-weighted imaging, mixed high and low signal intensity on fat-saturated images, and no significant diffusion restriction on diffusion-weighted imaging. ConclusionKHEs can occur in various locations and present as highly infiltrative and heterogeneous masses that can invade the skin, adjacent muscles, and bones. A vascularized mass with purpuric skin changes, with uneven and high T2WI signal is highly suggestive of the diagnosis of KHE.

Clinical and pathological analysis of 35 cases of ocular adnexal solitary fibrous tumor

Objective: To analyze the clinical and pathological characteristics and prognosis of 35 cases of solitary fibrous tumor of ocular adnexal (SFT). Methods: This was a retrospective case series study. The clinical data of 35 cases of ocular adnexal SFT was collected in Tianjin Eye Hospital from January 2000 to December 2020. The clinical manifestations, imaging examination results, pathological characteristics, treatment of patients were analyzed, and patients were followed up. All cases were classified according to the 2013 classification of World Health Organization of tumors of soft tissue and bone. Results: There were 21 males (60.0%) and 14 females (40.0%). The age range was 17 to 83 years, and the median age was 44 (35, 54)years. All patients were unilateral, with 23 (65.7%) in the right eye and 12 (34.3%) in the left eye. The course of disease ranged from 2 months to 11 years, with an a median duration of 12(6,36)months. Clinical manifestations included exophthalmos, limited eye movements, diplopia, and tearing. All patients underwent surgical treatment of complete resection of the tumor. Ocular adnexal SFT mostly occurred in the upper orbit (19 cases, 73.1%). On imaging examination, the tumor showed well-circumscribed space occupying lesion that heterogeneously enhanced with contrast, and abundant blood flow signals in the tumors. MRI showed isointensity or low signal on T1WI, and significantly enhanced on T2WI, presenting intermediate-to-high heterogeneous signals. The tumor diameter was 2.1 (1.5, 2.6) cm. There were 23 cases (65.7%) of classic subtype, 2 cases (5.7%) of giant cell subtype, 8 cases (22.9%) of myxoid subtype, and 2 cases (5.7%) of malignancy. Immunohistochemical staining showed that Vimentin, CD34 and STAT6 were positively expressed in all patients. Twenty-one cases (60.0%) showed positive expression of BCL-2, and Ki-67 positive index ranged from 1.0% to 10.0%. Tumors in this group were all low-risk according to the Demicco risk stratification. Follow-up was available for 25 patients with a duration of 2 years to 14 years and 7 months, and the median follow-up time was 88 (61, 124) months. Two patients relapsed, and no distant metastasis or death was observed. Conclusions: Ocular adnexal SFT mainly presents as a painless, slow-growing mass. And most of them are typical SFT. The imaging manifestations are varied Ocular adnexal SFT generally follows a benign course, with a good prognosis after complete excision. Recurrence could occur many years after surgery which requiring careful and long-term follow-up.

Novel Manifestation of Retinal Hemangioblastomas Detected by OCT Angiography in von Hippel-Lindau Disease

To elucidate the clinical characteristics of atypical retinal vascular proliferation in patients with von Hippel-Lindau (VHL) disease using OCT angiography (OCTA). Prospective, observational study. Fifty-seven consecutive patients with a diagnosis of VHL disease who visited Kyoto University Hospital between January 2019 and March2022. Retinal hemangioblastomas (RHs) were assessed using multimodal imaging including OCTA. Retinal hemangioblastomas were classified into 2 phenotypes: nodular and flat. Nodular RHs were defined as typical RHs that were globular, well-circumscribed tumors, often accompanied with dilated feeder arterioles and draining venules. Flat RHs lacked a protruded red or colored mass, had variable and indistinct borders, and were not accompanied with feeder and draining vessels. The prevalence, distribution, and description of atypical flat RHs. Among 57 consecutive patients with VHL disease, 37 patients (64.9%) showed RHs in at least 1 eye. Bilateral RHs were seen in 23 patients (62.2%). Among 58 eyes of 37 patients with RHs, typical nodular RHs were detected in 54 eyes. Nodular RHs were seen mainly in the peripheral retina and occasionally in the peripapillary region, and they showed exudative changes in some cases. Flat RHs were detected in 7 eyes (12.1%). Four eyes showed only flat RHs, and 3 eyes showed both types in the same eye. Most flat RHs appeared as retinal hemorrhages or faint flat abnormal retinal vessels in the inner retina on the fundus examination, often within the macula area or peripapillary. In all eyes with flat RHs, OCTA showed abundant blood flow in the lesions. OCT revealed that flat RHs were seen mainly between the retinal nerve fiber layer and the ganglion cell layer, and occasionally within the inner nuclear layer. During a mean follow-up period of 20.4 ± 15.0 months, no flat RHs accompanied exudative change, tractional retinal detachment, or progression in size. Patients with VHL disease can demonstrate 2 distinct types of RHs: the classic nodular type and an atypical flat type. OCT angiography can be useful in improving the detection of atypical flat RHs, which can be difficult to detect clinically. Proprietary or commercial disclosure may be found after the references.

Role of uterine biophysical profile in predicting conception in a sample of infertile women attending an IVF center in Erbil

Background and objective: Failure to get pregnant can be profoundly disappointing, frustrating and eventually lead to a lot of social, medical, and psychological consequences like depression. This study aimed to evaluate the role of uterine biophysical profile in predicting conception in women with a history of infertility. Methods: A prospective diagnostic accuracy study was conducted in Erbil, Iraqi Kurdistan region, in the Maternity Teaching Hospital from October 2019 to September 2020 on 51 women suffering from primary and secondary infertility. Vaginal ultrasound was performed for all the women at mid-cycle and before embryo transfer. The uterine scoring system for reproduction by Applebaum was calculated, and the total score was obtained. Its role in predicting conception was determined. Results: A cut-off of 15 scores of the uterine scoring system for reproduction gave a sensitivity of 86.7% and a specificity of 100%. Factors found to be associated with high rates of pregnancy were endometrial thickness 10-14 mm (P &lt;0.001), distinct trilaminar layer (P &lt;0.001), abundant blood flow within zone 3 (P &lt;0.001), and uterine artery Doppler PI of &lt;2.19 (P &lt;0.001). The last two parameters gave a pregnancy rate of 100%. Conclusion: Applebaum’s uterine scoring system for reproduction is an easy, simple, noninvasive method for predicting pregnancy in women suffering from primary and secondary infertility. Both uterine artery Doppler PI and endometrial receptivity (including thickness, character, and vascularity) are two important parameters in predicting suitable environment for implantation and pregnancy outcome. Keywords: Uterine scoring system for reproduction (USSR); Uterine biophysical profile; In-vitro fertilization (IVF); Intrauterine insemination.

Dermatofibrosarcoma protuberans misdiagnosed as sebaceous adenoma and incompletely resected in a child: A case report.

Dermatofibrosarcoma protuberans is extremely rare in children, making a correct diagnosis by clinicians is usually difficult due to its nonspecific manifestations, the recurrence of dermatofibrosarcoma protuberans after resection has always been a perplexing problem for clinicians. Ultrasound plays an irreplaceable role in the assessment of dermatofibrosarcoma protuberans, although there is a limitation in the diagnosis of the tumor. A 10-year-old boy led by his parents sought for surgical treatment because of the growing mass. Physical examination and preoperative ultrasonography showed that the mass was clear, and the routine resection of mass was performed. Six days postoperatively, histopathological examination indicated that the mass was dermatofibrosarcoma protuberans, and the peripheral and deep resection margins were positive. The patient was informed that a second extended resection was required. The second postoperative pathology showed a negative margin, and the patient was discharged. Postoperative follow-up was assessed by ultrasound examination, and the patient had no abnormalities. Dermatofibrosarcoma protuberans should be included in the differential diagnosis when the wide base subcutaneous lesion has suspicious features with high vascularity on ultrasound. If an ultrasound reveals a mass with abundant blood flow, clinicians should routinely perform the extended resection. Wide surgical excision may reduce the risk of reoperation and recurrence, and long-term follow-up is necessary to evaluate postoperative outcomes.

Imaging findings of retroperitoneal anastomosing hemangioma: a case report and literature review

BackgroundAnastomosing hemangioma is an uncommon benign vascular tumor that may be mistaken for a malignancy. The imaging findings of anastomosing hemangioma are not well provided from the previous reports. Herein, in the study, we discuss the imaging findings for one case of retroperitoneal anastomosing hemangioma.Case presentationOne 64-year-old female patient had a left retroperitoneal mass that was incidentally detected upon physical examination. A hypoechoic mass with abundant blood flow signals was found by US in the perirenal space. CT and MRI detected a large cystic and solid lesion in the left retroperitoneal space. Plain CT indicated that the internal density was uneven, and the pattern of enhancement was obvious and progressive. MRI-T2WI showed high intensity, DWI showed isointensity, and the mass also showed obvious progressive enhancement. Finally, anastomosing hemangioma was diagnosed via histopathological studies.ConclusionAs a rare and benign tumour, anastomosing hemangioma is easily misinterpreted. We suggest that the observation of “genitourinary tract related, well defined, hyperintensity or isointensity on T2WI, isointensity on DWI, and obvious progressive enhancement patterns likely to the vascular enhancement” may consider the diagnosis of AH.
