Osteochondroma of Upper Dorsal Spine Causing Spastic Paraparesis in Hereditary Multiple Exostosis: A Case Report

Abstract

Osteochondroma of the spine is rare. It may present in solitary or multiple form (hereditary multiple exostoses). Herein, we report a case of an 18-year-old male who was diagnosed with thoracic osteochondroma, originating from the D4 vertebra with intraspinal extension and spinal cord compression in hereditary multiple exostosis. The patient was managed with surgery. Complete tumour excision was done to relieve cord compression and recurrence. Postoperatively the patient's symptoms were improved. At 2.5 year follow-up patient is doing well without any recurrence.
