Abstract

Chronic recurrent multifocal osteomyelitis is a rare auto-inflammatory disease in children, with only a few reports of its association with other inflammatory diseases, such as systemic juvenile idiopathic arthritis. A 15-year-old boy was admitted due to fever, skin rash, arthritis, and high inflammatory factors and was finally diagnosed with systemic juvenile idiopathic arthritis. After 6 months of recovery from the disease, the patient was referred due to local pain and swelling in the arms and left thigh. In radiography, bone lesions were seen in the shoulders, left humerus, and left femoral diaphysis. A whole-body bone scan showed increased absorption in these areas, which suggested a tumor or osteomyelitis. A biopsy of the bone lesion of the left humerus confirmed sterile osteomyelitis. Although the co-incidence of chronic recurrent multifocal osteomyelitis with systemic juvenile idiopathic arthritis is rare, it should be considered in differential diagnosis. © The Author(s) 2024.
