Abstract

A case of chordoid meningioma occurring in a 61-year-old woman who did not have a Castleman's disease is presented. The patient had suffered from headache and motor dysphasia. Laboratory findings are normal. The tumor, located in the left frontal region and associated with peritumoral edema, was totally resected. Surgical specimen revealed a solid mass with irregular surface that measured 3.5 x 4.5 x 4cm. Immunohistochemical staining revealed that the tumor cells expressed epithelial membrane antigen(EMA) focally, but not S-100 protein and glial fibrillary acid protein (GFAP), and the Ki-67 proliferative index of the tumor was 9%. The neoplasm was diagnosed chordoid meningioma of the World Health Organization(WHO) grade II. After total resection, her preoperative headache and dysphasia were disappeared.
