Left: Axial FLAIR & T2WIs and a Sagittal T1WI demonstrate an extra-axial mass in the left
parietal region which is T1 isointense to gray matter and heterogeneously T2 hyperintense.
Local mass effect is seen with adjacent vasogenic edema. The clivus and the calvarium exhibit
heterogeneous marrow signal.
Left: Axial and coronal pre and post contrast T1WIs show that the mass enhances heterogeneously.
Also seen are adjacent regions of subarachnoid enhancement.
