Sternal Osteomyelitis with a Mediastinal Abscess Caused by Gemella <i>morbillorum</i> following Blunt Force Trauma

Abstract

Infections caused by Gemella morbillorum are uncommon. This organism is primarily associated with endocarditis and bacteremia and rarely with spondylodiscitis, arthritis, hepatic abscesses and meningitis. Sternal osteomyelitis caused by G. morbillorum has not yet been reported. We herein present a case of sternal osteomyelitis with a mediastinal abscess caused by G. morbillorum that occurred in a 74-year-old diabetic patient following blunt force trauma to the anterior chest wall. The patient was treated successfully with surgical excision and prolonged antibiotic treatment. Early recognition and timely intervention are important for managing life-threatening osteomyelitis of the sternum.
