Ptosis, INO. There is a nidus of enlarged and tangled blood vessels measuring up to nearly 4 cm within the left occipital lobe supplied by the left posterior cerebral artery and drained by the superior sagittal sinus via a superficial cerebral vein. There is associated mild surrounding susceptibility effect, as well as nonspecific punctate foci of susceptibility effect in the left temporal and right parietal lobe. However, there is no evidence for acute intracranial hemorrhage. There are several foci of T2 hyperintensity in the periventricular and subcortical white matter and a chronic right corona radiata lacunar infarct. There is no evidence of acute cerebral infarction. There is no midline shift or mass effect. There is mild diffuse cerebral volume loss.
1. Left occipital lobe arteriovenous malformation. Please refer to the recent CTA report for additional details.2. Chronic right corona radiata lacunar infarct and scattered foci of periventricular and subcortical white matter abnormality likely related to chronic small vessel ischemic disease, without evidence for acute ischemia.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
