We report an unusual tumor related to the meninges designated as a calcifying fibroma of the meninges. Our patient was a 44-year-old man. The tumor was located in the right frontotemporoparieta1 region and was excised totally via a right frontotemporoparieta1 craniotomy. The patient had recovered completely, and no recurrence was observed in a follow-up period of three years. Histopathologically, we noted scattered spindle cells among the hyalinized collagenous stroma, dystrophic-psammomatous calcifications, abundant perivascular hyalinization and cartilagenous metaplasia. Immunohistochemically, the tumor cells showed actin, smooth muscle and vimentin immunoreactivities. Ultrastructurally, spindle cells showed fibroblastic features.
