Mucinous cystic neoplasms of the liver involving the extrahepatic biliary tract is a rare slow-growing benign neoplasm of biliary system that has an early clinical presentation with obstructive jaundice. These tumors have a high risk of malignant transformation, which is difficult to diagnose preoperatively by radiology or endoscopy. We present a 31-year-old female patient who presented with complaints of pain abdomen, vomiting, fever, and obstructive jaundice. Ultrasound abdomen showed features suggestive of cholangitic abscess. Computed tomography abdomen showed features suggestive of cholangitic abscess and abrupt termination of the proximal CBD secondary to the stricture. A left hemi-hepatectomy was performed which showed a multiloculated cystic liver lesion with the involvement of extrahepatic duct, cystic duct, and proximal common bile duct. Histopathology showed cyst was lined by mucin secreting columnar epithelium without nuclear atypia, the wall the cysts showed ovarian-like stroma, and the diagnosis of mucinous cystic neoplasms of the liver and extrahepatic biliary tract with ascending cholangitis was made. Regular follow-up by clinical and radiological examination at 6 months did not reveal any recurrence.
