Figure 1. (A) High-resolution Axial T2 Fat sat sequences demonstrate hyperintense extra-axial lesion located in the left parasellar region, which extends to middle cranial fossa. The lesion partly encircles left distal ICA; (B) axial T1 W sequence shows iso-intense lesion; (C) post-contrast Axial T1 W sequences show marked homogenous enhancement; (D) perfusion map of CBV was obtained. High rCBV noted, demonstrating a highly vascular lesion. CBV: cerebral blood volume
