Gallbladder Agenesis Discovered Intraoperatively: About a Case

Gallbladder agenesis is a rare, little-recognized congenital anomaly, presenting in the form of hepatic colic in 23% of patients. The ultrasound assessment often describes a scleroatrophic vesicle, which can lead to unnecessary and potentially dangerous surgery. We report the case of a 64-year-old man, with no history of cholecystitis, presenting with hepatic colic and whose ultrasound diagnosis of scleroatrophic vesicle was questioned. patient was operated on by the traditional route for gallbladder lithiasis. The absence of a gallbladder was discovered intraoperatively. In order to confirm the diagnosis postoperatively, we performed magnetic resonance imaging (cholangio-MRI) which made the diagnosis of agenesis of the gallbladder.
