Solitary diverticular type V bile duct cyst.

Bile duct cysts are a rare form of biliary disease characterized by single or multiple dilations anywhere along the biliary tree. Todani Type V bile duct cysts are intrahepatic and typically involve multiple fusiform dilations. We present the case of a neonate with an unusual prenatally identified solitary diverticular type V bile duct cyst that was evaluated, monitored, and subsequently resected with right lobectomy at the age of 6 months. The importance of imaging in diagnosis and approaches to management are discussed.
