Mucinous biliary cystadenoma: A case report and review of the literature

Abstract

Mucinous biliary cystadenomas are rare neoplasms with protean manifestations. In most cases the mucinous material is retained within the cyst itself. We describe an asymptomatic case of a mucin secreting biliary cystadenoma in which the mucin presented as an amorphous intraluminal filling defect in the common hepatic duct on endoscopic retrograde cholangiopancreatography (ERCP). The neoplasm itself was confined to the posterior segment of the right hepatic lobe and was treated by formal right hepatic lobectomy. This case prompted a review of mucinous biliary cystadenomas.
