Chronic recurrent multi-focal osteomyelitis: a rare, inflammatory bone condition that causes episodes of pain and joint swelling. Fever may be present. The symptoms of CRMO typically begin in childhood and recur over time. It may affect a few sites or many sites within the body. CRMO may occur alone or in combination with other conditions like psoriasis or inflammatory bowel disease. In most cases CRMO resolves after many years without lasting complications, but it can sometimes cause delays in growth and permanent bone deformities.
Other names for chronic recurrent multi-focal osteomyelitis are CRMO; Multifocal osteomyelitis, chronic; Chronic multifocal osteomyelitis; CMO; Chronic nonbacterial osteomyelitis/Chronic recurrent multifocal osteomyelitis; and CNO/CRMO
