RESUMO
We describe a rare case of sclerosing osteomyelitis of Garré in a 63-year-old woman with uncontrolled right thigh pain. She had suffered from lower back pain and radiating pain on the right lower leg for a year and 4 months and so had spine surgery 8 months ago. But the right thigh pain persisted, and the levels of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) remained abnormal. Right femur radiographs showed cortical thickening on the proximal femur. Magnetic resonance images showed T2 hypersignal intensity lesions in the proximal femur. Under suspicion of osteoid osteoma or sclerosing osteomyelitis, surgery was performed with biopsy, bone curettage, and drilling. The culture was negative, and the biopsy showed chronic osteomyelitis. Despite surgery, the levels of CRP and ESR still remained abnormal. After using venous antibiotics, the pain subsided and CRP and ESR levels turned to normal. Followed by 6 weeks of oral antibiotics, pain was relieved after 1-year follow-up.
