 MRA BRAIN:Postsurgical changes related to transsphenoidal surgery with residual sellar and suprasellar mass with associated blood products as well as opacification of the paranasal sinuses as more fully characterized on 8/5/2016 MRI. There is minimally asymmetrically decreased caliber of the right internal carotid artery, developmental in etiology. No flow limiting stenoses are identified in the internal carotid arteries. A patent anterior communicating artery is visualized. The left A1 segment is asymmetrically decreased in caliber, a normal variant. The middle cerebral arteries are unremarkable. A right posterior communicating artery is visualized. A left posterior communicating artery is not definitively visualized. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.MRA NECK: There is a separate origin of the left subclavian artery, left common carotid artery, and brachiocephalic artery from the arch. The common carotid arteries and cervical internal carotid arteries are normal in course and caliber. Both vertebral artery origins are patent. There is no evidence of stenosis or occlusion.
1.Major intracranial arteries are patent without evidence of flow-limiting stenosis or aneurysm.2.Major cervical vessels are patent without evidence of flow-limiting stenosis.3.Postsurgical changes related to transsphenoidal surgery and residual sellar/suprasellar mass more fully characterized on 8/5/2016 MRI.
