A cyst or cavity in the spinal cord, which can expand over time. This may be idiopathic or develop secondary to trauma or spinal cord injury, intramedullary tumors, inflammation, vascular malformations, infection, Chiari malformation, or bony abnormalities. Symptoms depend on the location of the lesion; most occur in the cervical region. Some common symptoms of cervical syringomyelia include early impairment of temperature and pain sensation in a cape-like distribution on the back and arms, and loss of arm reflexes. There may also be chronic pain, loss of light touch, vibration, and joint position sense, weakness and atrophy of the hands, lower extremity spasticity and hyperreflexia. Bladder, bowel, and erectile dysfunction can occur as late manifestations. Prognosis depends on the underlying etiology as well as the location and extent of the lesion.

For more information on isolated syringomyelia, see OMIM.
