title: Torsion of the gallbladder.
abstract: BACKGROUND
  A 77-year-old woman was seen with progressive abdominal pain.
  
  
  METHODS
  A CT scan was made and showed a large gallbladder extending into the right lower abdomen. Ultrasound was performed but demonstrated no gallstones. Laparoscopy showed a tordated, necrotic gallbladder that was attached to the liver only by the cystic artery and cystic duct. Cholecystectomy was performed.
  
  
  CONCLUSIONS
  Torsion of the gallbladder is a rare but clinically important condition in which the diagnosis seldom is made preoperatively. In radiological and clinical signs of cholecystitis without gallstones, this condition should be considered.
