Myelography in patients with acquired immuno deficiency syndrome. Indications and results.

Neurological complications in patients with Acquired Immuno Deficiency Syndrome (AIDS) are frequent and in addition to central nervous system syndromes, involvement of the peripheral nervous system is increasingly seen. We evaluated the indications and results of myelographic examination in six AIDS-patients with signs of peripheral nervous system disease, out of 200 AIDS-patients with neurological complications. Five of these patients had a polyradiculopathy, with proven cytomegalovirus (CMV) infection in four cases. There were two abnormal myelographic examinations with findings of cauda equina nerve root involvement, both in patients with proven CMV-polyradiculopathy. These abnormal findings had no direct therapeutic consequences. Myelography is not essential for establishing the diagnosis, which is based on cerebrospinal fluid (CSF) analysis, but may be indicated to exclude a spinal cord or nerve root compressive lesion.
