A calcifying fibroma of the meninges - Report of a case and review of the literature

We report an unusual tumor related to the meninges designated as a calcifyi ng fibroma of the meninges. Our patient was a 44-year-old man. The tumor wa s located in the right frontotemporoparieta1 region and was excised totally via a right frontotemporoparieta1 craniotomy. The patient had recovered co mpletely, and no recurrence was observed in a follow-up period of three yea rs. Histopathologically, we noted scattered spindle cells among the hyalini zed collagenous stroma, dystrophic-psammomatous calcifications, abundant pe rivascular hyalinization and cartilagenous metaplasia. Immunohistochemicall y, the tumor cells showed actin, smooth muscle and vimentin immunoreactivit ies. Ultrastructurally, spindle cells showed fibroblastic features. The lesion is a true tumor and it should be kept in mind in the differentia l diagnoss of meningeal calcifying lesions.
