A Case of Notifiable Alithiatic Cholecystitis.

Acute alithiatic cholecystitis is an inflammation of the gallbladder without evidence of gallstones, often due to infection. It can occur at any age, and it is predominant in males. Listeriosis is a rare bacterial infection caused by Listeria monocytogenes (LM) through the ingestion of contaminated food such as dairy, legumes, and raw meats. Clinical presentations of listeriosis include bacteremia, meningitis, and gastroenteritis. Acute cholecystitis caused by listeria is even more uncommon, with only 23 cases reported in the literature. We present a case of a 65-year-old male, admitted to the Emergency Department with fever and altered state of consciousness which revealed bacteremia due to cholecystitis to LM. The patient was submitted to laparoscopic cholecystectomy and appropriate antibiotic coverage and was discharged seven days later. Early recognition and treatment of this disease are crucial for reducing morbidity and mortality.
