A case report of acalculous cholecystitis due to Salmonella paratyphi B.

Acute acalculous cholecystitis (AAC) is a rare condition occurring in only 5%-10 % of patients with acute cholecystitis. Systemic illness caused, for example, by E coli, Klebsiella pneumoniae, Vibrio cholera, and Salmonella species can result acute inflammation of gallbladder wall. It is a surgical emergency and if left untreated can lead to high mortality due to gangrene or perforation of gallbladder. We managed a 60-year-old female with clinical presentation of acute cholecystitis caused by Salmonella-induced gastroenteritis. Prompt use of radiological modalities such as computer tomography (CT scan) and ultrasound played an important role in pathologic diagnosis, overall follow up, and management of the patient.
