 There is mild motion artifact limiting evaluation. The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. Both vertebral arteries join to form the basilar artery. The anterior and posterior communicating arteries are present. There is no evidence of flow-limiting stenosis or aneurysm.Please note brain MRI was not obtained. There is soft tissue thickening along the inferior aspect of the left cavernous sinus and left anterior aspect of the petrous carotid canal which may correspond to reported history of schwannoma.
Mildly motion degraded MRA exam with no flow-limiting intracranial stenosis or aneurysm. Please note brain MRI sequences were not obtained as patient did not want to continue with the study.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
