Chronic recurrent multifocal osteomyelitis (CRMO) with symmetric involvement of both femora: X-ray, bone scintigram, and MR imaging findings in one case
The case of a 17-month-old boy with symmetric involvement of both femora in chronic recurrent multifocal osteomyelitis (CRMO) is presented. Imaging showed an extraordinary involvement of both femoral diaphyses and distal metaphyses with extensive lamellar-like periosteal reactions. Diagnosis was based upon laboratory tests, bone scintigraphy, and MRI findings and was proved by open bone biopsy.
