RESUMEN
Salmonella osteomyelitis occurs infrequently in children without sickle cell disease. Similarly, acute osteomyelitis of the epiphysis has been rarely reported. We present a case of primary epiphyseal osteomyelitis caused by Salmonella in the distal femur of an otherwise healthy 17-month-old child. Before isolating an organism, parenteral nafcillin provided ineffective clinical, radiographic, and laboratory responses. Repeated fluoroscopic-guided percutaneous surgical drainages allowed for identification of the Salmonella, but did not resolve the epiphyseal infection, as the infection focus was missed. In the effort to eradicate the infection yet minimize further trauma to the epiphysis, computed tomography-guided drainage was performed and the infection subsequently resolved. Owing to its greater localization accuracy and minimal invasiveness, the computed tomography-guided intervention allowed for precise drainage without compromising the contiguous growth plate. At latest follow-up, the patient was ambulating well, had a normal knee examination, and had no evidence of leg length discrepancy or growth disturbance.
