Syringomyelia is a disorder of the spinal cord caused by the formation of a cavity within the cord. The possible causes are trauma, tumors and congenital defects. It is most usually observed in the part of the spinal cord corresponding to the neck area. Symptoms are due to spinal cord damage and are: decreased sensation of touch, weakness and loss of muscle tissue. The diagnosis is confirmed with a spinal CT,
myelogram[?] or MRI of the spinal cord. The cavity may be reduced by surgical decompression.
