A case of chronic recurrent multifocal osteomyelitis in a 14-year-old girl is presented. The disease had an initial aggressive osteolytic appearance involving both the maxilla and the mandible. Conservative treatment with minimal surgical intervention has been successful in this case during a 2-year follow-up period. The value of magnetic resonance imaging and bone scintigraphy in this case and the cause of chronic recurrent multifocal osteomyelitis is discussed.
