The authors report a patient with a right sphenoid wing meningioma 16 years after a left convexity meningioma was removed. She had no evidence of von Recklinghausen's disease. Both tumors were benign. The literature on multiple meningiomas is reviewed.

For myelography to convey the maximum information regarding theca size and relationships, and to avoid flow artifacts and other false positives, the theca must be filled to the L1-L2 level and X-rays taken with the patient upright thus ensuring a static column of dye.
Approximately 80% of patients with spinal stenosis return to their usual occupations following decompressive laminectomy. It is essential to recognize distinctive features of stenosis on myelography and in accordance with the individual patients' clinical problems, to carry out an adequate decompression.
In contrast with patients with herniations of the nucleus pulposus, those with spinal stenosis experience onset of symptoms at a slightly older age; more males are affected than females. The symptoms tend to be somewhat more chronic, and therefore, the patients will have symptoms of back pain for a longer period of time before developing radiating root pains and will not come to surgical treatment until relatively late. Bilateral root symptomatology is more common although examination shows multiple nerve root involvement only slightly more frequently as well as involvement of the L1 to L4 nerve roots. The spinal movements tend to be somewhat better and straight leg raising tests are usually symmetrical and somewhat less restricted in those patients than in the acute disk syndrome. Postfusion and post-chemonucleolysis spinal stenosis will, of course, have the symptomatology of the initial problem, but their recurrent problems would tend to parallel those of spinal stenosis rather than disk herniation.
