Text in this example:
Transverse Myelitis Transverse myelitis is a neurological disorder caused by inflammation across both sides of one level, or segment, of the spinal cord. The term myelitis refers to inflammation of the spinal cord; transverse simply describes the position of the inflammation, that is, across the width of the spinal cord. Attacks of inflammation can damage or destroy myelin, the fatty insulating substance that covers nerve cell fibers. This damage causes nervous system scars that interrupt communications between the nerves in the spinal cord and the rest of the body.
Transverse myelitis may be either acute (developing over hours to several days) or subacute (developing over 1 to 2 weeks).
Initial symptoms usually include:
Localized lower back pain
Sudden paresthesias (abnormal sensations such as burning, tickling, pricking, or tingling) in the legs
Sensory loss
Paraparesis (partial paralysis of the legs).
Urinary bladder and bowel dysfunction is common. Thoracic Region
In patients with transverse myelitis, demyelination usually occurs at the thoracic level, causing problems with leg movement and bowel and bladder control, which require signals from the lower segments of the spinal cord.
