Retrospective evaluation of cone-beam computed tomography findings of odontogenic cysts in children and adolescents.

Odontogenic cysts develop from the epithelium of dental structures and generally grow slowly. In children and adolescents, cysts usually grow faster than adults and require much knowledge for diagnoses and treatments. This study aimed to determine the diagnosis and treatment of odontogenic cysts in different age groups by evaluating the type of lesions, age, gender, and anatomical distribution of odontogenic cysts seen in children and adolescents by cone-beam computed tomography. A total of 42 odontogenic cysts (radicular, dentigerous cyst, and odontogenic keratocyst) were determined in children and adolescents aged 7-18 years. Cone-beam computed tomography images of odontogenic cysts were analyzed in terms of types, age, sex, anatomical location, height, width, depth, scalloped borders, lesion shapes, tooth displacement, root resorption, and association with an unerupted tooth. There was a significant correlation between odontogenic cyst types and age groups, scalloped borders, lesion shape, tooth displacement, root resorption, and association with an unerupted tooth. When odontogenic cysts seen in children and adolescents are examined with cone-beam computed tomography, the radicular cyst was the most common form and was predominated in the 13-18 years age group and in boys. Differences in terms of scalloped borders, lesion shape, tooth displacement, root resorption, and association with unerupted teeth were noticed. The knowledge of the distribution and properties of odontogenic cysts in pediatric patients will help diagnose the lesions during clinical and radiological examinations and make appropriate treatment planning.

BACKGROUND Choledochal cysts are rare congenital dilatations of the biliary tract with an incidence of approximately 1 in 1000 live births. Most cases present with jaundice or other obstructive symptoms and are treated by surgical resection of the cyst and re-anastomosis. A liver biopsy at the time of surgery is mandatory to study the histological changes including fibrosis and to grade these changes to determine prognosis. We wanted to study the histology of liver biopsies received along with choledochal cysts, grade the hepatocellular damage and fibrosis, and correlate these findings with clinical presentation of the patients. METHODS 40 liver biopsies received along with choledochal cysts in paediatric patients were assessed for histological changes using 7 parameters including liver fibrosis and scored semi-quantitatively according to established scoring systems. These scores were correlated with the clinical data, age at surgery, sex of the patient, type of choledochal cyst, clinical features, and the results were analysed for their role in predicting patient prognosis. RESULTS We found that all the cases showed histological variations in the liver biopsy. Age of children showed an inverse relationship with histological scoring. Infants showed higher scores in comparison to older children. Fibrosis of the liver was also higher in Infants. Most of the cases presented with clinical jaundice. Patients with jaundice, pain abdomen, fever and acholic stools showed higher scores. We found that the sex of the patient and type of choledochal cysts were independent of the scores. CONCLUSIONS Younger age and more severe clinical presentation warrant an urgent surgical intervention in paediatric choledochal cyst. Histological assessment of the liver is mandatory to grade the hepatocellular changes including fibrosis and suggest prognosis and follow up of patients.

Neuroendoscopic treatment of arachnoid cysts in the paediatric population. Series results for 20 patients

IntroductionNeuroendoscopy has become an effective and safe treatment for arachnoid cysts in the paediatric population. We review the paediatric patients with arachnoid cysts treated by neuroendoscopy in our hospital and analyse the results. Material and methodsA retrospective analysis of 20 patients operated on from 2005 to 2018. The variables assessed are: gender, age, clinical presentation, cyst site, presence of hydrocephalus and/or extra-axial collections, endoscopic procedures and complications. Procedure success is defined as an improvement in symptoms and reduction in cyst size until end of follow-up. ResultsOur series comprised 13 males and 7 females (mean age: 64.6 months, range: 4–172 months). The most frequent site was suprasellar-prepontine (7), followed by intraventricular (6), quadrigeminal (3), interhemispheric (2) and Sylvian (2).A total of 70% (14/20) of patients had hydrocephalus at diagnosis, which increased to 85% in suprasellar-prepontine cysts and 100% in quadrigeminal cysts. Only 4/14 patients with required a ventriculoperitoneal shunt (median age at diagnosis: 12.5 months). Of these 4 patients, 3 developed severe shunt overdrainage.The procedure was successful in 60% (12/20) of the patients in the series. Success by location was 57% (4/7) in suprasellar cysts, 33% (1/3) in quadrigeminal cysts, 66% (4/6) in intraventricular cysts, 100% (2/2) in interhemispheric cysts and 50% (1/2) in Sylvian cysts. Treatment thus failed in 8 cases, with a mean time to failure of 12.12 months (range: 0–45 months). A new neuroendoscopic procedure was performed in 4 of these 8 cases (success in 2/4), a ventriculoperitoneal shunt was placed in 2 cases, a cystoperitoneal shunt was placed in 1 case and the remaining case was managed conservatively. Mean follow-up time was 52.45 months (range: 3–129 months). ConclusionsNeuroendoscopy is an effective and safe treatment for arachnoid cysts in paediatric patients that also enables managing associated hydrocephalus in most cases. The choice of neuroendoscopic procedure and success rate depend on cyst location. Younger patients have been found to have a higher shunt dependency rate. In these cases, measures to prevent shunt overdrainage are recommended.

Assessment of Incidentally Detected Simple Renal Cyst in Pediatric Patient Based on the Modified Bosniak Classification —Incidentally Detected Simple Renal Cyst in Pediatric

Renal cysts in pediatric patients are uncommon lesion. A modified Bosniak classification system for renal cysts based on US has been developed to evaluate pediatric renal cysts to identify the simple cyst or cystic tumour. Nevertheless, it is not widely used. In this retrospective study, all incidentally detected renal cysts by ultrasound performed in children and the reproducibility of modified Bosniak classification to guide the radiological and clinical follow up.

Emergent laparoscopic dome resection and omental suturing to the splenic parenchymal edge for a spontaneously ruptured non-parasitic large splenic cyst in a pediatric patient: a case report

BackgroundSpontaneously ruptured large splenic cyst is a rare in children, and traditionally total or partial splenectomy has been performed for treating an emergent case. We herein present a first case with spontaneously ruptured pediatric splenic cyst treated with emergent laparoscopic dome resection with omental suturing to the parenchymal edge of the spleen.Case presentationA 12-year-old girl with a spontaneously ruptured large non-parasitic splenic cyst (SC) was successfully treated by emergent laparoscopic dome resection with omental suturing to the edge of the splenic parenchyma. The patient presented with acute abdominal pain and was diagnosed with a ruptured non-parasitic SC and peritonitis by contrast-enhanced computed tomography (CT). Emergent laparoscopic dome resection of the SC and omental suturing to the splenic parenchymal edge were then performed. The protruding part of the cyst wall was completely resected using an ultrasonically activated device (USAD), and the greater omentum was then sutured to the anterior edge of the splenic parenchyma under a laparoscopic view. No complications were observed during the operation. A histological examination revealed a congenital splenic cyst lined by epithelial cells. The postoperative course was uneventful, and an ultrasound scan showed no evidence of cyst recurrence at 3 years after the operation.ConclusionsThis minimally invasive laparoscopic procedure was feasible and effective for treating a ruptured large splenic cyst in an emergent pediatric patient.

The use of localised CBCT to image inflammatory collateral cysts: a retrospective case series demonstrating clinical and radiographic features

IntroductionInflammatory collateral cysts are uncommon cysts primarily affecting first permanent molars during their eruption. There are diagnostic challenges that can be overcome with CBCT imaging. However, given the paediatric age group for this condition, there are patient cooperation and radiation dose factors to consider when justifying the scan. The aim of this case series study is to illustrate the value of CBCT in imaging and diagnosing inflammatory collateral cysts in paediatric patients, to highlight the need for a multidisciplinary approach for this uncommon pathological condition and to review the relevant literature.Case series description and resultsWe present three patients aged between 6 and 11 years of age with inflammatory collateral cysts affecting their first or second permanent molars for which CBCT imaging was utilised. All patients underwent cyst enucleation with preservation or extraction of affected teeth under general anaesthesia.DiscussionInflammatory collateral cysts are likely to be under reported given their indistinct clinical features and radiological signs. Conventional planar radiographs may not reveal this lesions size and full extent. CBCT overcomes these limitations; however, careful assessment of patient cooperation is needed and a low-dose protocol should be used.ConclusionsCBCT can provide useful imaging information which is difficult to obtain using conventional radiography, especially in cases where an inflammatory collateral cyst is suspected.

Re: Clinical Significance of Incidentally Discovered Renal Cysts in Pediatric Patients.

Clinical significance of incidentally discovered renal cysts in pediatric patients.

To determine the clinical significance of incidentally discovered renal cysts in pediatric patients and identify imaging predictors of autosomal dominant polycystic kidney disease (ADPKD). A retrospective search of radiology reports from 2000 to 2016 was performed to identify patients < 18years old with an imaging exam identifying at least one renal cyst and a ≥ 1-year follow-up renal imaging exam for cyst evaluation and/or diagnosis of ADPKD. Cysts with clear solid mass components were excluded. 84 pediatric patients with renal cysts were identified (mean age, 9.5 years), including 76 patients with incidentally discovered cysts and 8 patients with cysts identified from screening for ADPKD family history. Among the incidentally discovered cyst group, 7.9% were found to have ADPKD compared with 100% of patients with cysts and ADPKD family history. Maximum cyst diameter was significantly increased in patients with ADPKD compared to patients without ADPKD (22.0mm vs 12.7mm; P < 0.001, Fisher's Exact test). Multiple cysts or bilateral cysts were imaging features associated with a significantly higher (P < 0.01) incidence of ADPKD, both for the entire study population and the incidentally discovered cyst group. An increase in cyst size on the follow-up study was associated with higher incidence of ADPKD (P < 0.05). No malignancies were identified. Incidentally discovered renal cysts in pediatric patients are associated with a small but non-zero risk of ADPKD. Among cyst characteristics, bilaterality, multiplicity, large size, and increased size on follow-up imaging were associated with a statistically significant elevation of ADPKD risk, and should prompt diagnostic evaluation.

Prospective Comparison of MRI and Contrast-Enhanced MDCT for Evaluation of Pediatric Pulmonary Hydatid Disease: Added Diagnostic Value of MRI.

OBJECTIVE. The objective of our study was to prospectively investigate the diagnostic accuracy and added value of fast MRI for evaluating pulmonary hydatid disease in children by comparing fast MRI findings with MDCT findings. SUBJECTS AND METHODS. Twenty-eight consecutive children (24 boys and four girls; mean age ± SD, 8.93 ± 3.1 years; range, 5-17 years) with clinically suspected pulmonary hydatid disease were enrolled in this prospective research study for the period from October 2012 to July 2018. Fast MRI without contrast material and contrast-enhanced MDCT of the chest were performed within 48 hours of each other in all children. Two pediatric radiologists independently evaluated the lungs for the presence of consolidation, nodule, and mass (solid vs cyst). Cysts were further evaluated for the presence of fluid, air, and an internal membrane. The accuracies of fast MRI and MDCT for detecting pulmonary hydatid disease were obtained and compared. Interobserver agreement was measured with the kappa coefficient. RESULTS. The accuracy of fast MRI and MDCT for detecting pulmonary hydatid cyst was 92.86%. There was no difference between fast MRI and MDCT for accurately detecting pulmonary hydatid cyst (p < 0.001). Internal membranes were detected in 11 of 28 patients (39.28%) with fast MRI and three of 28 patients (10.71%) with MDCT. Almost perfect interobserver agreement was present between the two independent reviewers (κ = 1). CONCLUSION. Fast MRI without contrast material is comparable to contrast-enhanced MDCT for accurately detecting lung cysts in pediatric patients with pulmonary hydatid disease. However, fast MRI provides added diagnostic value by showing internal membranes of cysts, which is specific to pulmonary hydatid disease.

Thyroglossal duct cysts in children: a 30-year survey with emphasis on clinical presentation, surgical treatment, and outcome

Background: Thyroglossal duct cysts (TGDC) are one of the most common congenital anomalies found in the anterior neck region of children. Sistrunk’s procedure, described in 1920 already, is still considered as the gold standard. However, clinical reality shows that in a minority of patients, marsupialization and simple cyst excision are still performed as well. Cyst recurrence is the most feared complication. The main goal of this retrospective study is to determine risk factors of recurrence. Furthermore, data on presentation characteristics, management and outcome were collected as well.Methods: The data of 104 patients aged between 0 and 16 years who underwent surgery for TGDC at the University Hospital of Brussels between 1986 and 2016 were retrospectively analyzed. We focused on aspects of clinical presentation, intra- and postoperative treatment and long-term follow-up.Results: Overall recurrence of TGDC was seen in twelve of the 104 cases (11.5%). Eight out of these 12 showed a preoperative infection, 4 out of 12 had intra-operative cyst rupture. Five out of the 12 patients had not been treated by the Sistrunk procedure, but by cyst excision or marsupialization only. Non-adherence to the Sistrunk procedure appeared to be the only significant risk factor of TGDC recurrence.Conclusion: Our study shows that Sistrunk’s operation for thyroglossal duct cyst in pediatric patients is significantly superior in reducing the risk of cyst recurrence compared to other surgical treatments. Preoperative infection and cyst rupture did not influence the recurrence rates.

Surgical management for mesenteric cysts in pediatric patients: a single center experience

Background: Mesenteric cysts are exceptional abdominal lesions of childhood. Presentation may vary with broad spectrum of symptoms from asymptomatic mass and nonspecific complaints to an acute abdomen. Objectives of this study were to present a series of patients with mesenteric cysts and to analyze our experience with emphasis on the presentation, management, and outcome.Methods: This observational study included thirteen children were diagnosed and treated for mesenteric cysts. All cases subjected to clinical evaluation, laboratory investigations and radiological studies. The diagnosis was confirmed on laparotomy. Ethics committee approval was obtained. The main data which extracted and analyzed included demographic data, operative finding, postoperative complications and duration of hospital stay. Data were analyzed using SPSS for Windows software and P value of ≤ 0.05 was considered significant.Results: There were 13 patients with mesenteric cyst, 5 girls and 8 boys. The ages ranged from neonate to 8 years. Abdominal mass and pain was the main presenting symptoms. Prenatal diagnosis established in two cases. Laparotomy performed in all cases. Small bowel mesentery is the commonest site. Two patients required urgent surgery. Surgical procedures included cyst excision with or without intestinal resection. Chylolymphatic cyst was documented in 4 cases. Post-operative complications reported in 2 cases.Conclusions: Mesenteric cysts are unusual in children with variable clinical presentation. Complete excision was feasible in nearly all cases, bringing a favorable outcome. The possibility of this disease entity should be considered as the cause of acute abdomen.

Subcutaneoscopic Excision of External Angular Dermoid Cysts: Our Covert Scar Approach in 11 Cases.

External angular dermoid cysts, or epidermoid inclusion cysts, are a common subcutaneous tumor of the head and neck. For the majority of these lesions, excision is relatively simple and performed through an incision immediately overlying the mass. Facial lesions in pediatric patients present a unique challenge in that a direct approach carries the potential for visible scar formation. This article aims to detail our experience with subcutaneoscopic excision of external angular dermoid cysts in pediatric patients using endoscopic instrumentation. Retrospectively, we reviewed 11 cases, between the ages of 4 months and 3 years with external angular dermoid cysts. An incision is made on the scalp above the hairline, then a tunneled working space is created underneath the skin. 3 mm laparoscopy instruments were then used for providing excellent visualization and precise subcutaneoscopic dissection. There were no complications apparent in any of the 11 cases (except cyst rupture in one case), with mean procedure duration at 61 minutes. Final results at follow-up revealed aesthetically pleasing and well-healed skin incisions, hidden from view behind the hairline. The subcutaneoscopic technique utilizing endoscopic instrumentation has the advantage of improved visualization of the cyst, greater precision of dissection, and excellent cosmesis. One disadvantage of this procedure is that this involves learning a new technique while the majority of surgeons are already comfortable with the open approach. Given the safety and efficacy observed for this subcutaneoscopic procedure, this technique can have tremendous possibilities.

Clinical characteristics of pineal gland cysts in pediatric patients: A hospital based study

Objective − The aim of this study was to analyze the clinical characteristics of patients under 18 years diagnosed with pineal gland cysts. Methods − The study was conducted on a sample of 79 children and adolescents diagnosed with pineal gland cysts found among the 30,150 children treated at our Department in a 10-year period. We collected data for each child regarding gender, age, all pre-existing diagnoses, symptoms, all diagnostic methods performed in the patients and the type of treatment. Results − Out of 79 children, 47 had cysts whose size ranged from 0.51 to 1.0 cm. The most common symptoms associated with the pineal gland cyst were headache (21.5%) and general weakness (12.6%). The most common diagnoses leading to pineal gland cyst diagnosis were epilepsy (27.8%), change of psychological status (19%), headache (17.7%), tendency to atopy (11.4%) and obesity (10.1%). Most of the patients did not take drugs (44.3%), whereas 29.1% were taking one drug as chronic therapy. The most commonly used drugs were anticonvulsants (27.3%). Conclusion − Our study confirmed findings in adult patients with pineal gland cysts that headache and weaknesses, as well as diagnosis of epilepsy, are potentially related to pineal gland cyst diagnosis in children. Our conclusions may help accelerate the process of diagnosing these cysts and shorten the time of hospitalization, reduce the number of examinations and healthcare costs. Due to the rarity of this cyst, it would be desirable to repeat the research on a larger number of children.

Experiences in the Management of Choledochal Cyst in Pediatric Patients in a Tertiary Care Center of Bangladesh Armed Forces

Introduction: Choledochal cyst (CC) is a rare congenital abnormality of the biliary tract, for which there is no standardized surgical treatment. If left untreated it may cause bile duct (BD) obstruction to cholangiocarcinoma. For the commonest type of Choledochal cyst (Type I and IV) the treatment is surgery, although, the reconstruction technique of the BD has no gold standard.&#x0D; Objective: To assess the outcome of surgical treatment of choledochal cyst in pediatric cases in 8 years period in CMH Dhaka, a tertiary referral hospital of Bangladesh Armed Forces.&#x0D; Materials and Methods: This cross sectional study was carried out in the department of Paediatric Surgery at CMH Dhaka on 20 children of under 10 years having choledocal cysts. The study period was from March 2006 to February 2014.&#x0D; Results: Total of twenty patients aged 3 years to 10 years was included in the study. Out of them 14(70%) were females and 6(30%) were males. Fifteen (75%) patients presented with recurrent abdominal pain, 14(70%) with recurrent jaundice, 4(20%) patients with abdominal mass as initial symptoms. Twelve (60%) patients were diagnosed by Ultrasonogram (USG), rests were by Contrast Enhanced Computed Tomography (CECT) and Magnetic Resonance Cholangiopancreatography (MRCP). Eighteen patients presented with type 1 choledochal cyst and 2 of them had type IV choledochal cyst. All the patients were submitted to cyst excision and Roux-en-Y hepaticojejunostomy. Among them one patient required refashioning of anastomotic site to treat bile leakage.&#x0D; Conclusion: Early diagnosis and referral is essential to prevent complications and grave consequences and prognosis of these cases after surgery is good.&#x0D; Journal of Armed Forces Medical College Bangladesh Vol.12(2) 2016: 117-121

Laparoscopic approach of hepatic hydatid double cyst in pediatric patient: difficulties, indications and limitations

Purpose: Laparoscopic management analysis of a rare condition having potentially severe evolution, seen in pediatric surgical pathology. Aims: Outlining the optimal surgical approach method of hepatic hydatid double cyst and the laparoscopic method’s limitations. Materials and Methods: The patient is a 6 years old girl that presented with two simultaneous giant hepatic hydatid cysts (segments VII-VIII), having close vicinity to the right branch of portal vein and to hepatic veins; she benefited from a single stage partial pericystectomy Lagrot performed by laparoscopy. Results: The procedure had no intraoperative accidents or incidents. Had good postoperative evolution without immediate or late complications. Trocars positioning had been adapted to the patient’s size and cysts topography. Conclusions: The laparoscopic treatment is feasible and safe, but is not yet the gold standard for a hepatic hydatid disease due to certain inconveniences.

Mini Laparotomy with O Ring Wound Retractor Is a Minimal Invasive Approach for Resection of Dermoid Cysts in Pediatric Patients

To demonstrate the use of a mini laparotomy incision with an O ring wound retractor as a plausible minimally invasive procedure for removal of ovarian dermoids(mature teratomas) in preventing intraoperative rupture/spillage of cysts and preserving ovarian tissue in pediatric patients.

Treatment of Unicameral Bone Cysts in Pediatric Patients With an Injectable Regenerative Graft

Multiple treatment modalities exist for unicameral bone cysts (UBC), including steroid injection, autologous bone marrow injection, mechanical decompression, intramedullary fixation, curettage, and bone grafting. All have their own potential limitations such as high recurrence rates, cyst persistence, need for multiple procedures, and prolonged immobilization. A minimally invasive regimen consisting of curettage, decompression, and injection of a calcium sulfate-calcium phosphate (CaSO4-CaPO4) composite has been utilized at our institution in an attempt to obtain optimal results for the treatment of UBCs in the pediatric population. We retrospectively evaluated 16 patients with pathologically confirmed UBC who were treated with curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite between April 2006 and August 2010 at a single institution. The average age of the patients at time of surgical intervention was 9.4 years of age (range, 3 to 16 y). Average follow-up was 16 months (range, 6 to 36 mo). Radiographic healing, clinical outcomes, and complications were evaluated. Final follow-up radiographs demonstrated healing in 93.7% (15 of 16) of patients after a single procedure. Complete healing was observed in 14 of 16 patients and partially healed with a defect in 1 of 16 patients. One patient had a persistent cyst but did not wish to receive further treatment. All patients returned to full activities including sports on average at 3.1 months (range, 1 to 6 mo) and were asymptomatic on most recent follow-up. No postoperative complications, including refracture, were observed. Curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite for UBC in the pediatric population demonstrates encouraging results with low recurrence rates and complications compared with conventional methods. Case series, Level of Evidence IV.

Individual surgical treatment of intracranial arachnoid cyst in pediatric patients

Intracranial arachnoid cysts (IAC) are benign congenital cystic lesions filled with cerebrospinal fluid (CSF). This study evaluated microsurgical craniotomy and endoscopy in the surgical treatment of IAC. Eight-one consecutive pediatric patients with IAC were surgically treated between January 2004 and January 2011. The surgical procedures included microsurgical craniotomy and endoscopy. Symptoms at presentation, location of IAC, surgical treatment options, and effectiveness were evaluated. There were 43 males and 38 females and the mean age was 8.7 years (range between 1 month and 14 years) at the time of surgery. The cyst location was supratentorial in 72 patients and infratentorial in 9 patients, arachnoid cyst were identified. Follow-up period ranged between 2 and 8 years. Of the 49 patients with headache 83.67% of patients had cure and 10.2% had significant improvement. Of the eight patients with hydrocephalus and gait disturbances, six (75%) had complete total relief of symptoms and two (25%) patients had significant improvement. Four of the six patients with cognitive decline and weakness showed improvement. Of the 18 patients with epilepsy seizure freedom was: Engle class I grade I in 14 (77.78%) patients; class II in 2 (11.11%) patients; and class III in 2 (11.11%) patients. Follow-up studies from 2 to 8 years showed that headache was cured in 41 of the 49 cases (83.67%), significantly improved in 5 cases (10.20%), and showed no variation in 3 cases (6.12%). Hydrocephalus and gait disturbances were controlled in six of the eight cases (75.00%) and significantly improved in two cases (25.00%). Cognitive decline and weakness were obviously improved in four of the six cases (66.67%) and exhibited no variation in two cases (33.33%). According to the Engle standard, the following results were obtained from 18 patients with epilepsy: Grade I in 14 cases (77.78%); grade II in 2 cases (11.11%); and grade III in 2 cases (11.11%). Eleven cases with local or general enlarged skull exhibited no further progression. On follow-up computed tomography (CT) scan, there was variable alleviation of mass effect in all the 81 patients. Cystic size was significantly reduced in 65 patients with supratentorial arachnoid cysts and in 9 patients with infratentorial archnoid cysts. Twenty-one patients who had decreased skull thickness, had no further progression. Four patients who had cranioplasty had good outcome. The endoscopic approach was highly effective for most cases of IAC, particularly for cysts in the suprasellar and quadrigeminal regions as well as in the posterior fossa. Microsurgical craniotomy was recommended for IAC in the extracerebral convexity and intracerebrum. Local skull cranioplasty is needed for patients, or patients with preoperative diagnosis showed signs of cystic tumor and cyst-related epilepsy.
