chronic recurrent multifocal osteomyelitis: a case report

Introduction: chronic recurrent multifocal osteomyelitis (crmo) is a rare migratory skeletal disorder with non-infectious inflammatory etiology which usually causes bone pain in children and adolescents. intermittent periods of exacerbation and remission are usually noted during the course of the disease. it is a multifocal bone disease usually involving the metaphyses of long bones. the clinical and paraclinical findings are non-specific, and indeed crmo is a diagnosis of exclusion based on multiple criteria. case presentation: we present a 6-year-old boy with multiple periods of fever, systemic inflammation and bone pain since he was 2 years old, hospitalized multiple times, received antibiotics and finally diagnosed as a crmo case. conclusions: crmo should be diagnosed according to a variety of clinical and paraclinical findings. in children and adolescents with multiple bone lesions and lytic lesion, one of the differential diagnoses that should be considered is crmo.
