Multiseptate gallbladder. Report of a case with a review of literature

Multiseptate gallbladder is an extremely rare anomaly, the number of reported cases not having exceeded ten. In this 37-year-old man with a complaint of occasional nausea, vomiting and abdominal pain, intravenous cholecystography combined with tomography demonstrated a normal size gallbladder with many thin septa. The removed gallbladder had multiple intercommunicating locules divided by thin septa, looking like a honeycomb on the cut surface. The bile contained was dark brown in the neck and much lighter in color in the fundus, suggesting a disturbed bladder function. Histologically, some of the septa lacked the muscularis. He has been free of the previous complaints after surgery. Eight similar cases already documented are reviewed with a discussion on the embryogenetic aspect of this anomaly.
