What causes transverse myelitis?

Transverse myelitis has many different causes, often triggered by a variety of viral and bacterial infections (especially those associated with a rash such as measles or chickenpox). Transverse myelitis may be caused by viral infections, spinal cord injuries, immune disorders (including systemic lupus erythematosus, Sjogren's syndrome, sarcoidosis and multiple sclerosis) or insufficient blood flow through the blood vessels in the spinal cord. It may occur as a complication of such disorders as optic neuromyelitis, multiple sclerosis, smallpox, and measles, or as a complication of chickenpox or

rabies vaccinations.

TM can also accompany a variety of diseases that break down tissue that surrounds and insulates the nerves (demyelinating diseases), such as multiple sclerosis (MS).

Some toxic substances, such as carbon monoxide, lead, or arsenic, can cause a type of myelitis characterized by inflammation followed by hemorrhage or bleeding that destroys the entire circumference of the spinal cord. Other types of myelitis can be caused by poliovirus; herpes zoster; rabies, smallpox or polio vaccination; or parasitic and fungal infections.

Many experts believe that TM can occur without any apparent cause, probably as the result of an autoimmune process. This means that a person's immune system attacks the spinal cord, causing inflammation and tissue damage.

Regardless of the cause of the myelitis, onset of symptoms is sudden and rapid. Problems with movement and sensation appear within one or two days after inflammation begins. Symptoms include soft (flaccid) paralysis of the legs, with pain in the lower legs or back, followed by loss of feeling and sphincter (muscles which close an opening, as in the anus) control. The earliest symptom may be a girdle-like sensation around the trunk.

The extent of damage occuring will depend on how much of the spinal cord is affected, but TM rarely involves the arms. Severe spinal cord damage also can lead to shock.
