Gallbladder volvulus: Putting a spin on acute cholecystitis

First reported in 1898, gallbladder volvulus is rare. It occurs when the gallbladder twists on its longitudinal axis greater than 180 degrees, resulting in occlusion of the cystic vessels and duct. Herein, we describe the case of a 73-year old woman who was diagnosed with acalculus gallbladder volvulus, with the aid of computerised tomography. This was managed by urgent laparoscopic cholecystectomy and the patient continues to do well 15 months postoperatively. Although rare, a high index of suspicion of the condition must remain and a low threshold for imaging is needed to prevent the complications of gallbladder necrosis, perforation and biliary peritonitis.
