non glial tumor

Meningioma in a 27-year-old woman who presented with new-onset seizure. A, Axial unenhanced CT image demonstrates a large hyperdense extra-axial mass in the left temporal region with associated central calcification (black arrow) and surrounding edema. B, Axial enhanced CT demonstrates intense homogeneous enhancement. Distinction of intra- versus extra-axial mass by CT can be difficult. C, Axial T2-weighted MR image clearly demonstrates a CSF cleft around the circumference of the tumor (arrowhead) indicating this to be an extra-axial mass. D, Sagittal postcontrast Tl -weighted image demonstrates a dural tail anteriorly and posteriorly along the tentorium (white arrows). (Click to magnify figure)
