ABSTRACT
Since Lebert stated, in 1851, that fibroblastic and sarcomatous tumors of the intracranial cavity had different survival times, many neuropathologists tried to set up histopathological grading system predicting the prognosis of the tumor of the nervous system. Especially, the histological assessment of the aggressiveness of meningiomas has not always been useful in conforming the biological characteristics of these tumors, and the definition of malignancy is still subject to controversy. However, metastases from meningioma to remote sites have always been considered rarities. The authors experienced a case of metastatic meningioma, hemangiopericytic type, with a history of recurrence. A forty years old male patient received a craniotomy to remove a mass in right parasagittal region, in June 1981. He had suffered from Jacksonian type of seizure started from left foot throuth leg, thigh, and arm to face. During operation, a well defined mass was noted in left parasagittal region with cleavage plane. The tumor was completely removed with cauterization of invasion site. In microscopic examination, the mass had typical findings of hemangiopericytic type of meningioma. In September 1987, he received a repeat operation to remove a recurred tumor mass in vertex, at age of forty-six. The removed tumor revealed same histologic features as those seen in primary tumor. In January 1990, at age of forty-nine, he noted pain and tenderness on the right iliac crest and the left iliac tuberosity, Plain pelvis AP x-ray ad Pelvis CT scan revealed osteolytic expansile mass lesions involving both iliac bones, the body of second sacral vertebra, and the right superior ramus of the pelvic bone. An open biopsy of the iliac bone was performed. The microscopic findings of the bone lesion were same as reccruent lesion of the brain.
