title: [Isolated agenesis of the gallbladder: case report].
abstract: The gallbladder agenesis is a rare congenital abnormality which is frequently mistaken with cholecystolithiasis, regardless of the imaging modality used. The diagnosis is confirmed at laparoscopic surgery with intraoperative sonography and intraoperative cholangiography and postoperative MRI-cholangiography. Intraoperative cholangiography may be risky because the absence of normal anatomical structures and the impossibility of pulling on the gallbladder to dissect the triangle of Calot represents an increased risk of iatrogenic injury to biliary or portal structures. Therefore postoperative MRI-cholangiography seems to be a more suitable approach to confirm the diagnosis.
