Osteomyelitis complicating pyomyositis in HIV disease

Abstract

Pyomyositis has previously been described in association with human immunodeficiency virus (HIV) and as a discrete entity in HIV seronegative patients from tropical climates (tropical pyomyositis). Pyomyositis and osteomyelitis are usually considered a late complication of advanced HIV disease. We describe a patient with well-controlled HIV and both types of musculoskeletal infection. The case highlights an unusual presentation, the utility of MRI in soft tissue infection and an excellent outcome from prolonged antimicrobial therapy following surgical debridement.
