case_images: Preoperative MRI scans - (a) (Axial FLAIR image): Right sided rounded homogenous lesion with internal carotid artery draped over the tumor; (b) (T2W sagittal image): Lesion based on the posterior clinoid process, with internal carotid artery and perforators coursing over the tumor; (c) and (d) (T1W sagittal and coronal contrast images): Densely contrast enhancing tumor centered over the posterior clinoid process

case_images: On magnetic resonance imaging (MRI) examination, the lesion was hypointense on T1-weighted (T1W), hyperintense on T2-weighted (T2W), with homogenous contrast enhancement, centered over the PCP [Figure 1a-d].
case_images: (a) (Preoperative CT Angiography): Right posterior cerebral artery displaced posteriorly, and right internal carotid artery displaced anterolaterally; (b-d) (Postoperative T2W axial, T1W sagittal contrast, and T1W coronal contrast images): Demonstrating completely excised lesion with normal cisternal spaces

case_images: On MR angiography, the tumor was displacing the right P1 and P2 segments posteriorly and the ICA was displaced anteriorly and laterally [Figure 2a]. Postoperative MRI demonstrated complete excision of the lesion [Figure 2b-d].
