74-year-old female with cavernous malformation. Redemonstrated is a patchy subcentimeter area of enhancement in the lateral right putamen associated with a small anomalous vein. There is also a nonenhancing focus of 4 mm susceptibility effect in the medial right putamen. There is no evidence of acute intracranial hemorrhage or acute infarct. As before, there are a few scattered punctate to small foci of T2 hyperintensity within subcortical white matter locations without susceptibility abnormality. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
1.Findings suggestive of a subcentimeter right putamen cavernous malformation and associated developmental venous anomaly which are unchanged in appearance. 2.Probable minimal chronic small vessel ischemic disease.
