Brain. There is opacification of the distal internal carotid arteries, the distal vertebral arteries and the proximal anterior middle and posterior cerebral arteries. No intracranial arterial stenosis is appreciated. There is triplication of the anterior cerebral artery. The left A1 segment appears to bifurcate into the pericallosal artery and the left callosomarginal artery whereas the right A1 segment supplies the right callosomarginal artery. The right A1 segment is a little bit smaller than the left A1 segment. The anterior communicating artery is small to medium size. There is a 7.5 mm x 5.5 mm anteriorly directed aneurysm which originates at the anterior communicating artery region but specifically from the left side at the bifurcation of the left A1 segment into callosomarginal and pericallosal arteries. The aneurysm has a 2.5 mm neck. There is a 2.5 mm infundibulum at the origin of the right posterior communicating artery. The posterior communicating arteries are very small. The left superior cerebellar artery originates from the left P1 segment. There is extracranial origin of the left posterior inferior cerebellar artery. The right vertebral artery is larger than the left vertebral artery. The CSF spaces are appropriate for the patients stated age with no midline shift. The patient is status post nasal cavity surgery with removal of the anterior aspect of the nasal septum, anterior nasal spine of the maxilla and some of the right-sided nasal cartilage. Periventricular and subcortical white matter hypodensities of a mild degree are present. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma. The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
