Osteochondromas make up about 30% to 40% of benign bone tumors. Most are solitary lesions but some are multiple, usually with autosomal dominant inheritance. From 1% to 4% of osteochondromas occur in the spine, where they can cause a variety of signs and symptoms, including those of spinal cord compression. Isolated osteochondromas are usually of little significance. However, if they are located near neural structures, they may cause irritation due to mechanical compression. In patients with hereditary multiple exostoses who present with neck or back pain, and particularly in those who have neurologic symptoms in the upper or lower extremities, a diagnosis of intracanalicular osteochondroma should be presumed until proven otherwise. Computerized tomography(CT) and MRI are the imaging procedures of choice. Prompt surgical excision affords the best prognosis for these patients who have spinal cord compression secondary to intracanalicular osteochondroma.
