A Large hepatic Peribiliary Cyst -A Case Report

Peribiliary cyst is a poorly recognized and under-reported clinico-pathological entity around the biliary tree. Peribiliary cysts are cystic dilatations of obstructed peribiliary glands, which are normal elements of the biliary tract. They are generally asymptomatic and rarely cause biliary obstruction. They are usually discovered incidentally at autopsy. A 77-year-old female patient presenting with abdominal pain and abdominal distension for 1 month duration due to a large hepatic peribiliary cyst is re-ported here. Radiological(CECT) imaging demonstrated a large cystic lesion with septation occupying Right hypochondrium and Right lumbar region, arising from right lobe liver displacing the liver medially but not communicating with the bile duct. Our pre op diagnosis was either hydatid cyst or simple liver cyst .Laprotomy with de-roofing of the cyst was performed and histological examination of the cyst wall revealed a Non-Neoplastic Cyst - Peribiliary gland cyst . The patient made an uneventful recovery and remained asymptomatic with normal liver function tests 8 months postoperatively
