A case of hypoplastic gallbladder

Abstract

Hypoplastic gallbladder is an extremely rare congenital anomaly. We report a case of hypoplastic gallbladder that was diagnosed preoperatively. A 36-year-old man was admitted to our affiliate hospital for right hypochondralgia. Although cholecystitis was suspected, US and CT failed to detect the gallbladder. He was referred to our hospital for further examination and treatment US and CT showed a small structure on the liver bed. EUS clearly revealed a consecutive small cystic structure to the cystic duct ERC demonstrated the structure continued with cystic duct. Since clinical symptom was not improved, open cholecystectomy was performed. Pathological examination revealed that the resected specimen has normal wall structure which is consistent with gallbladder. Preoperative symptoms disappeared after surgery.
