54 years, Female, Reason: 3 t scanner moyamoya unilateral History: headache and tingling in upper extremities. MRI BRAIN
1. No evidence of acute infarct. Chronic infarct involving the left frontal corona radiata with mild extension into the basal ganglia. There are additional mild chronic small vessel ischemic changes.2. Cystic lesion involving the right aspect of the sella which also appears to present on remote CT from 2009. Further delineation with pituitary MRI can be considered as clinically warranted.3. The left internal carotid artery is moderately diminutive developmentally with suspected superimposed high-grade stenosis/occlusion involving the left distal supraclinoid ICA extending into the left M1 and to a lesser degree proximal left A1 segments. There are mildly prominent left-sided lenticulostriate collateral vessels. Overall findings are consistent with a moyamoya pattern. 4. Left parieto-occipital scalp defect.
