[Malignant meningioma with extracranial metastasis].
We report case of malignant meningioma involving the lumbar vertebra (3rd and 4th). A 53-year-old man who developed occipitalgia in April 1977 was operated under the diagnosis of posterior fossa tumor in August 1977. The tumor was totally removed macroscopically Simpson grade 2. The histological diagnosis was malignant meningioma, He complained of lumbago and right leg pain since June 1981. Destruction and tumor stain of the 3rd and 4th lumbar vertebrae were recognized on CT scans. In May 1982, surgical decompression and spinal fixation were attempted. The surgical specimen was verified as a malignant meningioma. Therefore, he underwent irradiation therapy to the lumbar spine (total dose 50 Gray). He presented with occipitalgia in March 1983. CT scan detected tumor recurrence in the suboccipital region. The recurrent tumor was totally removed immediately. The histological feature was malignant meningioma. The mode and site of metastasizing meningioma are discussed with a review of the literature.
