Painful Scoliosis Secondary to Posterior Rib Osteoid Osteoma: A Case Report and Review of Literature

Abstract

Osteoid Osteoma is the most common benign bone tumor often observed in long bones. Ribs involvement is very rare. In spinal involvement, it usually can cause painful scoliosis often seen in posterior component of spinal vertebral. A 15 year-old female with painful scoliosis, whose brace treatment was unsuccessful, is presented. In imaging investigations, her CT scan showed lytic lesions in the posterior of the seventh rib. She had a 30-degree painful scoliosis with right concave curve. Posterior part of the rib containing tumoral lesion was removed. Histopathological investigations showed a woven bone. Osteoid Osteoma was confirmed and the patient’s pain was resolved several days after the surgery. Follow-up in 3 month after the surgery showed that the curve of spinal deformity was completely resolved. Rib osteoid osteoma can cause painful scoliosis in young people, and surgical excision can be a successful treatment. It seems that application of brace had no impact on reducing the patient’s symptoms.
