Acute cholecystitis with Listeria monocytogenes.

Listeriosis, an opportunistic food-borne disease caused by Listeria monocytogenes, is infrequent and occurs preferentially in patients at the extremes of age, during pregnancy or in immunocompromised hosts. Most common manifestations are maternofoetal and neonatal infections, severe invasive presentations such as bacteraemia with or without central nervous system symptoms occuring preferentially in immunosuppressed patients and self-limited gastro-enteritis affecting healthy individuals. Exceptionally, focal infections such as cholecystitis are described. We report here a case of acute cholecystitis caused by Listeria monocytogenes in an 82-year-old woman. Thanks to a successful treatment: cholecystectomy and antimicrobial therapy (amoxicillin plus clavulanic acid), the patient soon recovered. This case-report provides an opportunity to review the current literature concerning the association of Listeria monocytogenes and cholecystitis.
