C2 intraspinal osteochondroma causing spinal cord compression in a patient with multiple hereditary exostoses

Intraspinal osteochondroma causing neurological manifestations is a rare condition and can present as either solitary osteochondroma or more commonly as a part of multiple hereditary exostoses. We report a case of osteochondroma arising from lamina of C2 in a 21-year-old patient with multiple hereditary exostoses causing spinal cord compression and cervical myelopathy. The patient presented with worsening neurological deficit and an inability to walk. Immediate laminectomy and surgical decompression were done after accurately localizing the lesion through computed tomography and magnetic resonance images. Following excision of the lesion, the patient recovered completely. The case report is followed by a review of literature highlighting the incidence of spinal osteochondroma, location preferences, clinical presentation, diagnosis, and results of decompression.
