BACKGROUND: Hereditary multiple exostosis is a benign disorder characterized by multiple osteochondromas affecting long and flat bones, although occasionally vertebral column involvement can be seen. Cervical spinal cord compression in HME is a rare condition. The objective of this manuscript is to describe a rare case of cervical myelopathy due to an exostosis arising from C7 in a patient with HME and a comprehensive review of the current literature. CASE DESCRIPTION: We describe a case of HME in an 18-year-old girl with myelopathy characterized by quadriparesis due to an osteochondroma arising from the lamina of C7. The patient underwent surgery, and a laminectomy was performed with a complete removal of the exostosis and spinal cord decompression. One month after surgery, patient presented an excellent recovery without neurologic deficits. CONCLUSIONS: Cervical spinal cord compression resulting from osteochondroma is an extremely serious complication of HME. Neurosurgical approach should be recommended in order to achieve a spinal cord decompression, which usually results in excellent functional recovery.
