Meningeal Solitary Fibrous Tumor

• Lee JM

Abstract

We report a rare case of a patient with meningeal solitary fibrous tumor. A 60-year-old woman presented with right leg monoparesis. Brain magnetic resonance imaging demonstrates a well enhancing huge mass, located in left parietal lobe. Cerebral angiography demonstrating increased vascularity in area of the tumor, which had feeder vessels extending from the internal carotid artery and external carotid artery. A presumptive diagnosis of meningioma or hemangiopericytoma was considered. At surgery, the consistency was firm and had destroyed the dura and skull. A gross total resection was performed. Immunohistochemically, tumor was strongly, and widely, positive for CD34 and vimentin. There was no staining for epithelial membrane antigen(EMA), S-100 protein, cytokeratin, and glial fibrillary acidic protein (GFAP). Differential diagnosis of intracranial solitary fibrous tumor includes fibroblastic meningioma, meningeal hemangiopericytoma, neurofibroma, and schwannoma.
