Retroperitoneal Schwannoma

Schwannoma is a benign tumour of peripheral nerve sheath. It usually arises from head, neck, and trunk. Retroperitoneal schwannoma is a rare entity, accounting for only 0.3–3% of total schwannomas. Majority of retroperitoneal schwannomas reported in literature have a diameter of 5 to 15 cm. Preoperative diagnosis is difficult due to low frequency, nonspecific clinical course, and nonspecific imaging features. Histology usually provides definitive diagnosis. Schwannomas are solitary, well-circumscribed, and noninvasive, so complete surgical excision provides good result. We report a case of a 23-year-old male, who presented with progressive abdominal distension and intermittent episodes of intestinal obstruction. CECT was suggestive of huge solid-cystic mass in abdominopelvic region. Image guided percutaneous aspiration revealed around 1 litre of frank pus and FNAC was suggestive of abscess. Exploratory laparotomy revealed a large 32 × 28 × 26 cm mass with solid and cystic components containing 1 litre of pus. Histological features of tumour were suggestive of benign schwannoma and immunohistochemistry for S-100 was positive. Postoperative recovery was uneventful. We report this case of a retroperitoneal schwannoma because of giant size, rare location, unusual presentation, and diagnostic dilemma.

Background. Solid pseudopapillary neoplasm of the pancreas is an uncommon exocrine pancreatic tumor of epithelial origin, which represents only 1% to 2% of all pancreatic tumors and mainly affects young women. Objective. To describe clinical and imaging features of these rare entity in a symptomatic young woman. Case report. 41-year-old female patient, without morbid history, consulted for intermittent epigastralgia of one-month evolution. Abdominal ultrasound and magnetic resonance imaging demonstrated the presence of a solid-cystic mass of neoplastic appearance in the body-tail of the pancreas. The case was presented to the institutional hepato-biliary committee where surgical resection was decided. Discussion. Although solid pseudopapillary neoplasm of the pancreas are very uncommon pancreatic tumors, it is necessary to keep them within the differential diagnosis on the one hand due to their low but existing malignant potential and on the other hand due to their good prognosis with surgical treatment.

Abstract A female fetus of a dizygotic pregnancy presented with a retrovesical cystic mass at 16 weeks. Severe and recurrent fetal ascitis developed at 25 weeks. Pre-eclampsia, probably due to mirror syndrome, precipitated fetal extraction, which led to severe prematurity complications and neonatal death. Necropsy showed: cloacal anomaly, anal atresia, ambiguous genitalia and bicornuate uterus.

Background: Vascular anomalies comprise a widely heterogeneous group of lesions. Diagnosis and management of these lesions present challenges to the surgeons, radiologists and histopathologists. Accurate classification of these lesions results in appropriate therapy. Aim of the study is to study the role of histopathology and histochemical stain in the diagnosis of vascular malformationMethods: The present study is a hospital based observational study on vascular malformations over a period of three years from 2016 to 2018 done in department of Pathology and Plastic Surgery at tertiary care centre, Visakhapatnam.Results: Out of 107 specimens of vascular anomalies received, 72 cases were vascular neoplasms, 35 were vascular malformations. Majority of the vascular malformations were seen in the cervicofacial region (43%) followed by extremities (37.1%). Most common malformation in the present study was arterio venous malformations (60%) followed by venous malformations (22.8%). Verhoeff’s VanGieson stain demonstrated discontinuity of internal elastic lamina in cases of arteriovenous malformation and helped in differentiating the lesions from capillary malformation and vascular tumors.Conclusions: Histopathology, special histochemical stains along with imaging features can be used to reduce diagnostic difficulties and in helping proper management of vascular malformations.

Critical Intervention

Prenatal ultrasound diagnosis of a cloacal malformation Cloacal malformations are a spectrum of rare congenital disorders caused by the arrest of the cloacal division during different stages in early embryogenesis. They necessitate critical intervention at birth, posing important surgical challenges. The majority unfortunately remains undetected during prenatal screening. Knowledge about sonographic red flags, however, may improve antenatal detection and therefore postnatal outcome as a result of a timely referral to multidisciplinary tertiary centers. A 29-year-old patient presents at the hospital due to decreased fetal movements in the third trimester of pregnancy. The ultrasound reveals an anechoic bilobed cystic mass with a thick midline septum within the pelvis of a female fetus. The diagnosis of a cloacal anomaly with associated duplicated vaginas and uteri is made. Severe accumulation of urine lies at the base of bilateral hydrocolpos, peritoneal ascites and a urinary tract obstruction with an adverse influence on both pulmonary and renal development. The baby is prematurely delivered by an emergency caesarean section. Her condition is poor, requiring immediate respiratory resuscitation. An explorative laparotomy on the following day confirms the diagnosis. The first steps towards anatomical correction are taken. It may be concluded that the triad of bilateral hydronephrosis, a pelvic cystic mass and an absent normal bladder within a female fetus should always raise suspicion of a cloaca.

Abstract Backgroud: We present our experiences, particularly long term followup, of 20 patients who underwent operations for BCA or BCAC over the last 15 years in an effort to formulate more effective management strategies Methods: Clinical data on patients with pathologically confirmed BCA or BCAC between June 2002 and May 2017 were retrospectively analyzed. Results: Twenty patients were pathologically diagnosed with intrahepatic BCA (12) or BCAC (8); the mean ages for these 2 groups were 46.3 years and 62.0 years, respectively (P = 0.000). The main imaging feature for most BCA patients (83.3%) was cystic mass with septations. The main imaging features for BCAC were unilocular or unilocular cysts with papillary projections or solid portions. All BCAC patients received surgical treatment. No BCA patients developed recurrent cystadenoma after complete excision. Five (62.5 per cent) of the 8 BCAC patients died during a median follow-up time of 61.8 months. Three deaths were due to metastasis. The median follow-up of BCAC patients without a recurrence was 90.7months (range 31–152). Conclusions: Factors associated with a higher likelihood of BCA or BCAC include being a middle-aged or older woman, having elevated serum CA19-9 levels, showing high-risk features on imaging, and having recurrent liver cyst(s). Radical excision is recommended to obtain long-term tumor-free survival.

Abstract Purpose To improve the accuracy of the preoperative diagnosis of ovarian cystadenofibroma (CAF) or adenofibroma (AF). Methods Clinical symptoms, laboratory results, imaging features, and pathological results of 11 patients with 11 histologically proven ovarian CAF/AF were reviewed retrospectively. The computed tomography (CT) and magnetic resonance imaging (MRI) features of the tumor including location, number, size, internal characteristics, CT density or MRI signal intensity, enhancement performance, lymphadenopathy, and amount of ascites were comprehensively evaluated. Results With regard to the clinical findings, results of serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and other laboratory tests were normal in most cases (81.8%, 9/11). The imaging features of the 11 lesions were as follows: unilateral occurrence, well-defined boundary, round or roundish, unilocular (63.6%, 7/11), cystic mass (81.8%, 9/11), multilocular (27.3%, 3/11), black sponge sign (18.2%, 2/11), carpet sign (81.8%, 9/11), residual ovary sign (45.5%, 5/11), papillary nodule clusters (45.5%, 5/11), and small vesicle with an acute angle to the inner cyst wall (18.2%, 2/11). The signal intensity of the solid component was isointense or hypointense on T2-weighted imaging and hypo intense on diffusion-weighted imaging. The CT value of the lesions ranged from 21 Hounsfield units (Hu) to 45 Hu. A slight to moderate enhancement degree occurred in more than half of the lesions (54.5%, 6/11). No or a small amount of ascites was present in these cases. Histologic examination revealed SCAF (45.5%, 5/11), SAF (27.3%, 3/11), and borderline CAF/AF (27.3%, 3/11). No necrosis, hemorrhage, or calcification was observed in any of these masses. Conclusion Ovarian CAF/AF usually mimics malignancy, demonstrating a cystic mass combined with solid component on CT or MR images. The integrity of case data including laboratory results and imaging features can help radiologists make an accurate preoperative diagnosis. No or a small amount of ascites may narrow the differential diagnosis.

Abstract Background Ovarian carcinosarcomas (OCS) are very rare tumors composed of a mixture of carcinomatous and sarcomatous elements. There have been only scattered case studies that have described the imaging findings. In order to improve the awareness of this rare tumor, this study aimed to analyze the clinical and imaging features of five cases of OCS confirmed by surgical pathologic evaluation. Methods This retrospective study includes five OCS patients diagnosed and treated at our institute. The clinical course and imaging findings of all patients were retrospectively analyzed. The patients were 31 to 59 years of age. All five patients underwent CT scans, two underwent MRI scans. Results The five patients have no specific symptoms. Four patients had elevated CA 125 levels and three patients had elevated CA 153 levels. All patients had unilateral tumors, four in the left ovary, one in the right ovary. The largest transverse diameter of the tumors ranged from 11 cm to 14 cm. Two tumors showed solid masses with unequally sized cystic areas or necrosis, one showed a multilocular cystic mass with a large solid protrusion, two tumors showed a larger cystic mass with multiple mural nodules. The solid components of the tumors demonstrated restricted diffusion (the average ADC value being 998 mm2/s and 1102 mm2/s, respectively), and showed moderate or obvious enhancement. All five patients were treated by surgical resection and adjuvant chemotherapy. One patient is currently undergoing post-operative chemotherapy 1 month after operation and clinical stable. Three patients survived and showed no obvious recurrence and / or metastasis in follow-up from 9 to 59 months. One patient died from recurrence and metastasis. Conclusions OCS are rare and demonstrate variable CT and MRI morphological appearances. Due to the heterogeneous nature and very low morbidity of OCS, combination of careful analysis of imaging findings and clinical features might be useful for a more accurate diagnosis of OCS.
