Meanwhile, strangulated cholecystitis is extremely rare, and it develops when the gallbladder is strangled by a band. It is very similar to gallbladder torsion in terms of imaging findings and obstruction of blood and biliary flow, and it requires emergency surgery. We herein report a case of a 90-year-old woman with gallbladder strangulation caused by a fibrotic band due to a chlamydia infection, and we also reviewed some literature on strangulated cholecystitis.
