Strangulated cholecystitis with imaging findings similar to those of gallbladder torsion: A case report.

Cholecystitis is a common disease, but the occurrence of gallbladder strangulation is extremely rare. Here, we report a case of an 88-year-old woman with strangulated cholecystitis caused by an intraperitoneal band. Computed tomography (CT) scan revealed a constriction of the gallbladder body and marked wall thickening at the fundus. Additionally, the finding suggested torsion at the constricted area, which we diagnosed as gallbladder torsion. Cholecystectomy was performed immediately, and the diagnosis was strangulated cholecystitis caused by a band. The imaging findings of strangulated cholecystitis are similar to gallbladder torsion, making it difficult to diagnose preoperatively. We will discuss the imaging findings of strangulated cholecystitis and gallbladder torsion.
