[Chronic non-infectious osteomyelitis in children].

Musculoskeletal pain in common and the differential diagnosis is broad. It is important to recognize the harmful and/or treatable pathology, without performing unnecessary diagnostics. Pattern recognition is crucial. One of the differential diagnostic considerations is chronic non-infectious osteomyelitis (CNO). A relatively unknown auto-inflammatory disease. By presenting three cases, we want to draw attention to this condition and contribute to a better recognition of this disease. We emphasize the importance of doing a total body MRI, when CNO is considered.
