Perforated Gangrenous Gallbladder in an Asymptomatic Patient.

Acute cholecystitis or inflammation of the gallbladder is a common cause of hospitalizations. A percentage of those patients will progress to gangrenous cholecystitis and perforation. This medical emergency can lead to peritonitis, which has increased morbidity and mortality. The first-line modality for the diagnosis of acute cholecystitis is an ultrasound, but if it is inconclusive, then a computed tomography (CT) scan may be beneficial. Gangrenous cholecystitis and perforation have been reported in asymptomatic diabetic patients secondary to diabetic neuropathy and/or gallbladder ischemia leading to nerve denervation. Yet, here we present the case of an asymptomatic non-diabetic patient with gangrenous gallbladder perforation that was treated with antibiotics and drain placements. Diagnosis and treatment involve the collaboration between primary care, interventional, and diagnostic services to appropriately manage these patients. This case demonstrates that clinicians should have a low threshold to conduct CT scan of the abdomen, especially when there is a sudden resolution of pain.
