Three patients were studied with a 0.3 T superconducting magnet to assess the role of magnetic resonance (MR) imaging in the recognition and evaluation of diastematomyelia and associated abnormalities. Comparison was made with other imaging techniques, including metrizamide computed tomographic (CT) myelography. With MR imaging, the divided spinal cord was well imaged in its entire craniocaudal...

We evaluated the nerve roots of the cauda equina by CT myelography in 36 patients aged from 11 to 19 years with lumbar disc herniation. On straight-leg-raising tests, six younger patients had isolated hamstring tightness with no sciatica (group A) and 30 had sciatic pain (group B). CT myelography showed that no patient in group A had associated nerve-root swelling, and that the roots were displ...

Adhesive spinal arachnoiditis is a rare condition of several causes, including complications of myelography. An experiment was conducted to study the effects of surgical glove powder contamination in the cerebrospinal fluid. The subarachnoid space of 45 rabbits was injected with either a suspension of powder from sterile surgical gloves, Pantopaque (iophendylate), or a combination of the two ag...

scribed in 1960 (1), is a very rare disease because the bony pelvis provides an effective shield against external injury. Thus, pelvic ring fracture or hip dislocation (1) usually precedes lumbosacral nerve root avulsion. Isolated lumbosacral nerve root avulsion is so rare that, to the best of our knowledge, only nine cases have been reported in the English literature to date (2). The diagnosti...

Intracranial hypotension is a rare cause of persistent headache mostly originating from a dural CSF leak. If a conservative treatment fails, a minimally invasive EBP can lead to a successful sealing of such a leak. Independent of the leakage site, an EBP is usually applied at the lumbar level with varying success. We used CT myelography to detect the site of the dural leakage, then immediately ...
