Primary sternal osteomyelitis in an immunocompetent adolescent.

Primary sternal osteomyelitis is an uncommon but challenging condition that frequently poses diagnostic difficulties. Imaging plays a crucial role in both diagnosing the condition and assessing potential complications. Treatment typically involves a combination of surgical drainage and a prolonged course of antibiotics. We report the case of a 17-year-old immunocompetent male who presented with chest pain. Laboratory investigations revealed elevated inflammatory markers, and blood cultures, along with contrast-enhanced computed tomography, confirmed the diagnosis of primary sternal osteomyelitis. The patient was started on dual antibiotic therapy and underwent surgical drainage, with subsequent favorable clinical and radiological progression.
