Abstract
A n osteochondroma is a bone tumor, but rarely occurs in the thoracic spine, especially in the pediatric population. The objective of this study was to describe the diagnosis and successful treatment of a pediatric patient with an osteochondroma of the thoracic spinous process. The anteroposterior and lateral plain radiographs illustrated a well- defined solid mass arising from the spinous process of the tenth thoracic vertebrae. Computed tomography and magnetic resonance imaging further delineated that the mass arose from the spinous process, but with no obvious impingement of the nerve roots. A fter excision of the lesion, the gross pathological and histological evaluations were consistent with those of an osteochondroma. This led to appropriate surgical intervention, resulting in definitive treatment.
