Multiseptate gall-bladder: incidental diagnosis on ultrasound.

Multiseptate gall-bladder is a very rare congenital condition, and fewer than 30 cases are reported in the literature. Most patients are female adults though it can occur in children and men. Although usually symptomatic, a case is described of a patient diagnosed incidentally on ultrasound. In the former group it is important to recognize because cholecystectomy is curative. Biliary calculi are usually absent in multiseptate gall-bladder while choledochal cysts have been associated.
