Gangrenous cholecystitis (GC) is a severe and potentially deadly complication of acute cholecystitis. We present a 83-year-old gentleman with a past medical history of type 2 diabetes mellitus with significant associated neuropathy, presenting to a community hospital in a major metropolitan area with 10 days nausea and vomiting and a benign abdominal exam. While the patient was admitted for hyperglycemia, he was subsequently found to have severe GC requiring urgent surgical intervention.
