title: Gallbladder torsion resulting in gangrenous cholecystitis within a parastomal hernia: findings on unenhanced CT.
abstract: Gallbladder torsion is a rare cause of acute gangrenous cholecystitis; its occurrence within an abdominal hernia has not been previously reported. We present such a case occurring within a parastomal hernia and imaged with unenhanced CT.
