Chronic recurrent multifocal osteomyelitis.

We report what is, to our best knowledge, the first case of chronic recurrent multifocal osteomyelitis (CRMO) in which the frontal and sphenoid bones were involved. Characterized by a prolonged and fluctuating course of osteomyelitis at different sites, CRMO is self-limited, although sequelae can occur. The diagnosis is one of exclusion. It is important to publish cases like this, because the recognition of CRMO can prevent aggressive surgical and medical treatment.
