There are punctate ill-defined hypodensities in the left pons as well as left cerebellar deep white matter, compatible with evolving acute ischemic infarcts better demonstrated on previous MRI. There is no acute intracranial hemorrhage. The ventricles and sulci are within normal limits. There is no midline shift or mass effect. There are no areas of pathological enhancement. There is no extraaxial fluid collection. The visualized portions of the paranasal sinuses and mastoids or middle ears are grossly clear. There is moderate luminal narrowing of the cavernous segment of the left internal carotid artery. There is more diffuse irregularity and mild to moderate narrowing of the cavernous segment of the right internal carotid artery. The middle cerebral arteries are unremarkable. There is hypoplastic left A1 segment. The right anterior cerebral artery is unremarkable. There are small bilateral posterior communicating arteries. There is hypoplastic right P1 segment of posterior cerebral artery. P1 segment of the left PCA is not well-visualized. The basilar artery is diffusely irregular and severely thin in caliber. The V4 segment of the right vertebral artery is not visualized. There appears to be a right AICA visualized. There is marked irregularity and luminal narrowing involving the post-PICA portion of the left V4 segment, with the distal tip not visualized. There is no definite right PICA visualized. The left AICA is diminutive. CTA NECK
