Ectopic hypoplastic and multiseptate gallbladder with coexisting choledochal cyst: evaluation with sonography and magnetic resonance cholangiopancreaticography.

Multiseptate gallbladder, a rare congenital anomaly, may exist as an isolated anomaly or may coexist with other biliary system anomalies. We report a case of a multiseptate, ectopic, hypoplastic gallbladder associated with a choledochal cyst. The diagnosis was made using sonography and magnetic resonance cholangiopancreaticography.
