Abstract:

Tubular adenoma of common bile duct (CBD) is an extremely rare benign extrahepatic bile duct adenoma. We report a case of surgery and histopathological proved CBD tubular adenoma. A 69-year-old man was admitted to the hospital for yellow urine for one month. Clinical, radiological and laboratory results were analyzed. Medical literature in PubMed pertaining to similar cases was reviewed. A solid mass was detected in the distant part of CBD, with dilation of the extrahepatic and intrahepatic bile duct by ultrasound, contrast enhanced ultrasound (CEUS), computer tomography (CT) and magnetic resonance imaging (MRI). It showed heterogeneous enhancement both in contrast-enhanced CT, MRI and CEUS. After operation, pathological findings indicated a tubular adenoma of CBD. Our case highlighted the fact that tubular adenoma of CBD was demonstrated as a homogeneous mass in the distant part of CBD.
