Abstract

Osteoid osteoma (OO) is a benign bony tumor characterized by presence of a nidus of osteoid vascular bone with dense sclerotic bone in its periphery. Osteoid osteoma which usually localize within long bones, comprises 10% of all benign bone tumors, 1% of all spinal tumors, and infrequently located in thoracic spine. A spinal osteoid osteoma usually presents as dull back pain localized around level of lesion that is worse at night, paraspinal muscle contracture maybe causing postural scoliosis. The definitive diagnosis is based on the clinical symptoms associated with CT-scanner, MRI and confirmed by postoperative histopathology. There are several methods used so as to treat osteoid osteoma such as conservative management, percutaneous intervention using CT-guidance or tumor resection surgery. However, the appropriate treatments for osteoid osteoma in spine depend on particular cases. We report an osteoid osteoma in T₂ vertebral spine in 17-year-old patient who underwent thoracic pedicle screw fixation with T₂ laminectomy and tumor resection via a posterior approach thereby reviewing the literature on this disease.
