title: Extrahepatic biliary cystadenoma: a rare cause of biliary obstruction.
abstract: Biliary cystadenoma is a rare tumor of the biliary tree and a rare cause of obstructive jaundice. Most are intrahepatic, and pure extrahepatic biliary cystadenoma is less common. Cases are more common in women. Unless suspected, diagnosis of extrahepatic biliary cystadenoma is often delayed. Here, we report the case of a young woman with extrahepatic biliary cystadenoma who presented at Raja Isteri Pengiran Anak Saleha Hospital with obstructive jaundice initially thought to be due to a large biliary stone based on the endoscopic cholangiogram image. She was successfully managed with resection of the cystadenoma.
