Chronic recurrent multifocal osteomyelitis--report of eight patients.

The authors undertook a retrospective review of the clinical records and radiologic findings of eight children with chronic, recurrent multifocal osteomyelitis (CRMO). This disease is a recognized clinicopathologic entity with typical radiographic findings, mostly in the metaphyses of the long bones. The diagnosis is one of exclusion without pathognomonic findings. The patients were treated with non-steroidal anti-inflammatory drugs. There was no evidence of altered bone growth or abnormal joint development. It is concluded that CRMO is a distinct clinical entity that is different from acute or subacute bacterial osteomyelitis. Recognition of this condition is important to avoid treatment with antibiotics and repeated operations.
