title: [Gallbladder torsion. A case report].
abstract: BACKGROUND
  The unusual anatomical position of the organ, generally suspended by a mesentery, allows the rare possibility of its torsion with necrosis and even perforation.
  
  
  METHODS
  A woman, aged 78, who presented signs and symptoms similar to those of severe acute cholecystitis: abrupt onset of pain and a large palpable mass below the right costal margin. Immediate laparotomy with detorsion and easy cholecystectomy was performed.
  
  
  CONCLUSIONS
  Should a greatly enlarged mass be palpable below the right costal margin within a few hours from the abrupt onset of unremittant abdominal pain the possibility of torsion should come to mind not to delay operation in the supposition of acute cholecystitis.
