Parasellar solitary fibrous tumor of meninges: magnetic resonance imaging features with pathologic correlation.
Solitary fibrous tumor (SFT) is a benign mensenchymal neoplasm of spindle-cell origin. The authors report the case of a 50-year-old man with SFT arising from the meninges of the left parasellar region with cavernous sinus involvement. The tumor was demonstrated isointense on T1-weighted and heterogeneously hypointense on T2-weighted magnetic resonance imaging (MRI) with strong contrast enhancement. The preoperative MRI diagnosis was meningioma or hemangiopericytoma. Pathological study revealed an SFT that stained positive immunohistochemically for CD34 and vimentin.
