Fig 3. A, Axial T2-weighted TSE image shows the relatively hyperintense meningioma in the right CPA with a broad base against the petrous bone (arrow). Note the vasogenic edema of the adjacent cerebellum and middle cerebellar peduncle (star). B, On axial T1-weighted SE, the tumor is isointense to the brain. C, Postcontrast T1-weighted image at the corresponding level shows intense enhancement of the tumor (arrow). D, Axial T2*-weighted GRE does not show hypointense signals characteristic of microhemorrhage in the tumor (arrow). The tumor matrix appears homogeneous. E, Photomicrograph showing features of a meningioma in which neoplastic cells are displayed in concentric whorls and lobules of varying sizes. These neoplastic cells are supported on a vascularized connective stroma (H&E x150).
