59-year-old with history of cerebral cavernous malformations and prior hemorrhage experiencing headaches. Redemonstrated are innumerable foci of susceptibility effect within the supratentorial and infratentorial brain. As before, the largest lesion measures up to 10 mm in the right inferior frontal gyrus. No lesions demonstrate perilesional edema. A new lesion visible with T2 technique is present within the left cerebellar hemisphere measuring 2-3 mm, without perilesional edema. There is no extra-axial hemorrhage or acute infarction. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift. The expected intracranial vascular flow voids are present, without evidence of associated developmental venous anomalies. The skull and extracranial soft tissues are unremarkable. There is no abnormal enhancement.
1.A new cerebral cavernous malformation visible with T2 technique is present within the left cerebellar hemisphere measuring 2-3 mm, without perilesional edema, suggesting interval microhemorrhage, however likely not recent.2.Otherwise stable multiple supratentorial and infratentorial cerebral cavernous malformations.
