5Başkent University, School of Medicine, Pathology Department, İstanbul, Turkey Osteoid osteoma is a benign skeletal neoplasm composed of osteoid and woven bone. The majority of the lesions arise in the cortex of long bones. Osteoid osteoma of the spine is a rare primary spine tumor and those located at the thoracal spine are even rarer. The usual treatment involves complete resection, including the nidus, or alternatively radiofrequency percutaneous ablation is performed. The authors present a 32-year-old female with an unusual localization of the osteoid osteoma in the thoracal spine where imaging modalities were not conclusive for the diagnosis. The T1 vertebra lesion was successfully resected via a posterior approach with T1 laminectomy, including right side C7 and T1 foraminotomies, and vertebroplasty were performed. Histopathology reported the lesion as an osteoid osteoma. Keywords : Osteoid osteoma, Scintigraphy, Spine
