A Deceptively Quiet Case of Gangrenous Cholecystitis.
Acute gangrenous cholecystitis is a severe complication of acute cholecystitis. We report a 70-year-old male with type 1 diabetes mellitus who presented with intractable vomiting without abdominal pain. CT imaging showed gallbladder wall thickening and concern for gallbladder perforation. Patient underwent a laparoscopic cholecystectomy, which revealed a gangrenous gallbladder with surrounding purulent drainage. The patient recovered after an extended hospital course. This case highlights the importance of considering atypical presentations of severe intra-abdominal pathology in diabetic patients.
