Abstract
INTRODUCTION: Chronic recurrent osteomyelitis (CRO) is a rare disease characterised by unifocal or multifocal aseptic inflammatory bony lesions. OBJECTIVE: To evaluate clinical features and response to treatment with non-steroidal anti-inflammatory drugs in patients with CRO. MATERIALS AND METHODS: A 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. RESULTS: Multifocal 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. CONCLUSIONS: The 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.
