Two cases of chronic recurrent multifocal osteomyelitis: radiological and scintigraphic findings.

Chronic recurrent multifocal osteomyelitis (CRMO) is an extremely rare condition, of uncertain aetiology. Since first described, in 1972, under 100 cases have been reported. It is being reported with increasing frequency, and many cases of this disease go unreported. It most commonly affects patients in childhood or adolescence. No infective agent has been identified, and antibiotics do not affect the course of the disease. We present the cases of two female children with this disorder, describe the radiological and scintigraphic findings and review the literature. Case 1 is the first reported case to our knowledge of CRMO presenting with cranial nerve palsies.
