title: [Multiple spinal neurinomas without von Recklinghausen's disease: report of three cases].
abstract: Multiple spinal tumors are relatively rare and account for from only 1.2 to 9.5% of all spinal tumors. Half of the multiple spinal tumors are accompanied with von Recklinghausen's disease. Since March 1983, we have encountered 31 spinal tumors including 11 neurinomas, three of which were multiple and showed no manifestations of von Recklinghausen's disease. The incidence of multiple spinal tumors was 9.7% in our series. Altogether, 40 cases of multiple spinal neurinomas without von Recklinghausen's disease have been reported including our three cases. According to those 40 cases, much neurinomas occur 5 times more frequently in men than in women, and they are found predominantly in the lumbosacral region. In the present paper, we describe three cases of multiple spinal neurinomas, and compare the results of several neuroradiological examinations. Myelography was the most reliable method to determine whether or not the tumors were multiple. However, in cases where myelography was completely blocked out, other neuroradiological methods such as metrizamide-CT scan or MRI with Gd-DTPA intravenous injection were able to bring us information concerning multiplicity.
