Twistin' the night away: gallbladder torsion accompanying large bowel malignancy.

Gallbladder (GB) torsion is a rare surgical emergency seen in the elderly. It occurs due to the rotation of the gallbladder along the axis of the cystic artery and cystic duct. This study aimed to report a case of an acute GB torsion in an elderly female patient diagnosed by multi-detector computed tomography (MDCT). The clinical and imaging features of GB torsion, which can be used to assist in the preoperative diagnosis, were also discussed with emphasis on CT criteria.
