The tethered conus is probably a rather unknown entity. Every patient, adult or child, with spinal dysraphia, presenting an unexplained progressive urological, neurological and/or orthopedic disturbance can have a tethered cord. With lumbar myelography using metrizamide it is possible to diagnose the low positioned conus and its tethering causes. A review of the clinical symptoms and diagnostic radiology, illustrated with myelographic evidence, is given.

Nine patients with redundant lumbar nerve root syndrome were identified using positive-contrast myelography, seven with metrizamide and two with iophendylate. Serpiginous intradural filling defects occurred in conjunction with a complete or partial extradural block and spinal stenosis. These redundant nerve roots were seen on the cephalic side of the block. Eight of the nine patients had pseudoclaudication. One case was found incidentally during a cervical myelogram. This series is presented to demonstrate the characteristic myelographic pattern that should be recognized and differentiated from tortuous intradural blood vessels. Possible causes are discussed.

The importance of accurate diagnosis of epileptic manifestations, even if unusual, as complications of diagnostic metrizamide exploration of the CSF space is emphasized on the basis of 2 case histories.
