AIDS presenting as radial bone tuberculosis and pyogenic methicillin-sensitive Staphylococcus aureus osteomyelitis

Abstract

Osteomyelitis is a rare initial presentation of HIV. We report a case of a 25-year-old, apparently well man presenting with a traumatic, pathological fracture of the right radius. He had a 2-week history of low-grade fever, swelling and purulent discharge of the radial aspect of his right forearm. Osteomyelitis, secondary bacteraemia and pneumonia were clues that led physicians to test for HIV. Multiple debridement, sequestrectomy and vacuum-assisted closure were done. Tissue cultures revealed Mycobacterium tuberculosis (TB) and methicillin-sensitive Staphylococcus aureus He was treated successfully with 6 weeks of culture-guided intravenous oxacillin, staphylococcal decontamination and first-line anti-TB regimen (rifampicin, isoniazid, ethambutol, pyrazinamide). Antiretroviral agents were started thereafter. Successful infection control and preservation of limb functionality was achieved with a multidisciplinary team approach. To our knowledge this is the first reported case of an adult patient with HIV presenting with tuberculous and pyogenic osteomyelitis of the radial bone.
