Chronic recurrent multifocal osteomyelitis (CRMO) is a rare non-infectious autoinflammatory disorder typically seen in young women. We describe the case of a young man who presented at 13 years of age with pain in the tibia, humerus, clavicle and hip. Worsening of the condition through clinical presentation and radiographic imaging was observed over 10 years. Radiographic imaging initially showed some sclerotic changes, but worsened to osteolytic lesions of the proximal tibia, elevation of the lateral cortex and thickening of the anterior cortex. Bone biopsy of his right anterior proximal tibia showed no infection or neoplasia. But, laboratory results showed elevation of inflammatory markers such as erythrocyte sedimentation rate or C-reactive protein. The patient was diagnosed with CRMO and treated with antibiotics for suspicion of chronic bacterial osteomyelitis. Chronic bone pain, abnormal imaging and elevation of inflammatory markers suggesting that chronic bacterial osteomyelitis can lead to difficulties with the diagnosis of CRMO.
