Mucinous Cystadenoma of Liver with Mesenchymal Stroma

Hepatobiliary cystadenoma is a rare benign cystic tumor of the liver. These are predominantly located in right hepatic lobe. A 45 year old female presented with abdominal pain, epigastric discomfort, fever and vomiting. On radiological evaluation USG showed large multiloculated cystic mass in right lobe of liver. Contrast Enhanced CT examination exhibited exophytically growing multiloculated cytic lesion with differential content and peripheral capsular and central enhancement with imaging diagnosis of hydatid cyst was given. The surgical excision of hepatic cyst was done. On histopathology reported as mucinous cystadenoma of liver with mesenchymal stroma. We are presenting this case for its rarity, clinical, radiological and histopathological findings.

Primary peritoneal hydatid cyst is a rare entity. A 42 yr old parous female presented with painless lower abdominal lump since 6 months. On clinical examination an immobile abdominopelvic lump of the size of 18-20 weeks pregnant uterus with bosselated surface was noted. Ultrasound Sonography Test (USG) and Contrast Enhanced Computerized Tomography Scan (CECT scan) of abdomen and pelvis revealed large multilocular abdominopelvic cystic mass in continuity with RT ovary. Radiologically a differential diagnosis of hydatid cyst and mucinous cystadenoma was made. All relevant ovarian tumor markers were normal. Serology confirmed increased Echinococcus IgG antibodies (196.60 U/ml, ELISA). The patient underwent complete surgical excision of the lump. Histopathology and Hematoxylin and Eosin (H and E) staining of the aspirate from the cyst confirmed the diagnosis of hydatid cyst. Since no other organs were involved it was diagnosed as a case of primary peritoneal hydatid cyst. The hydatid cyst may mimic an ovarian cyst, thus it is important to keep this rare entity in mind as a differential in ultrasonographically diagnosed pelvic cystic lesions.

Uncommon Tumor

Benign cystic mesothelioma (BCM) is an uncommon tumor. A 9-year-old girl presented with acute abdominal pain and vomiting for the last 24 hours. Ultrasound abdomen and contrast enhanced CT scan were suggestive of cystic lesion. At laparotomy, a cystic mass arising from the peritoneum was found, which was excised completely. On histopathological examination it was diagnosed as benign mesothelioma.

Twenty-seven cystic renal cell carcinomas (RCC) in 23 patients were analyzed radiologically and histologically. They were classified into 4 histopathologic growth patterns: a) multilocular (n = 15, 9 with macrocystic and 6 with microcystic components); b) unilocular (n = 3); c) cystic necrosis (n = 9); and d) tumors originating in the wall of a simple cyst (n = 0). Macrocystic multilocular RCC showed multiloculated configuration on ultrasound and contrast enhanced CT. Angiography revealed neovascularity peripherally or within the tumor (7/9 tumors). Microcystic multilocular RCC did not fulfill the criterion for a cystic mass on ultrasound: they were irregularly hyperechoic. There was little enhancement on postcontrast CT and only slight neovascularity on angiography. Unilocular RCC showed a cystic mass with an irregular wall or mural nodules on ultrasound and contrast enhanced CT. Necrotic RCC showed various sonographic findings from anechoic to irregular echoic. The appearance on CT varied from cystic with mural nodules to a multiloculated or irregular architecture. Neovascularity was seen in the periphery in 8 of 9 tumors. Clinically, this type seemed to be the most aggressive.
