Abstract
A case of Cryptococcus neoformans osteomyelitis involving both the femur and rib is reported. A 50-year-old male presented with a 1-month history of a persistently painful right hip. Radiography revealed an osteolytic area in the subcapital region of the right femoral neck and trochanteric region, and magnetic resonance imaging (MRI) revealed an intramedullary lesion in the peritrochanteric region. A Tc99m whole body bone scan showed significantly increased uptake in the posterior aspect of the right 7th rib as well as the right femoral region. Hemiarthroplasty with a bipolar prosthesis was performed. Because a permeative osteolytic lesion was identified intraoperatively, surgical resection was also performed. A culture from intraoperative specimens yielded C. neoformans. The rib infection was not treated surgically. Intravenous fluconazole was administered postoperatively. The patient became seronegative for cryptococcal antigen with no further illness over the next five years.
