Chronic recurrent osteomyelitis (CRO) is a rare disease characterised by unifocal or multifocal aseptic inflammatory bony lesions.ObjectiveTo evaluate clinical features and response to treatment with non-steroidal anti-inflammatory drugs in patients with CRO.Materials and methodsA retrospective assessment was conducted on 5 children with OCR over a period of 8 years. They had been diagnosed based on clinical, laboratory findings, histological study of injuries, and imaging test.ResultsMultifocal disease was observed in 40% of cases, and unifocal in 60%. The large majority (80%) were male, with a mean age at diagnosis of 13 years (range: 11–15 years). The bones most frequently affected were the clavicle and tibia, representing 18.2%. The most common presenting symptom was pain in all patients, with fever being present in 20% of cases. Imaging studies such as CT and MRI were effective in 100%, and in all cases the biopsy reported a lymphoplasmacytic infiltrate. After a mean follow-up of 5.9 years, there was a good treatment response in 100%, with a mean recurrence at 5.25 months being observed.ConclusionsThe anodyne results of most clinical studies to assess CRO, and the similarity in clinical presentation of this with many infectious or tumour diseases makes its diagnosis a real challenge. On the other hand treatment with NSAIDs can be considered a good initial therapeutic option.
