Perforation of the gallbladder is a rare but dreaded complication following cholecystitis.1 Spontaneous perforation is most commonly seen in the elderly, and in patients suffering from diabetes mellitus.2 The most common site of perforation is the fundus of gall bladder.3 The gall bladder distension and edema associated with acute inflammation leads to venous and arterial obstruction. Subsequently, this leads to ischaemia and necrosis of the gall bladder wall. The fundus is most susceptible to this injury due to maximum distance from the cystic arterial supply. Aggravating factors include atherosclerosis, focal vasospasm and localized vasculitis. If diagnosed and treated late, perforation of gallbladder may be associated with high chances of morbidity and mortality.4-6 Here, we report a case of a 66-year-old male with perforation of gallbladder following acute calculous cholecystitis.
