75-year-old male with cavernous malformation. Redemonstrated is hemosiderin staining associated with the site of prior intraparenchymal hemorrhage involving the left postcentral gyrus. This is unchanged in configuration with a prior examination, as is the closely associated smaller focus of hemosiderin staining and high T2/FLAIR signal within the left precentral gyrus. A left cerebellar hemispheric lesion has also been stable. There are multiple stable foci of high T2/FLAIR scattered within subcortical/ventricular white matter without associated susceptibility abnormality. There are no new lesions including mass, foci of acute hemorrhage, hydrocephalus, enhancement or acute ischemia. The midline is intact. Normal flow-voids are demonstrated within major intracranial vessels. Orbits, sinuses and mastoid air cells are unremarkable.
1.Stable encephalomalacia and hemosiderin staining involving the left precentral gyrus possibly related to an underlying cavernoma.2.Two other hemosiderin-stained lesions within the left frontal lobe and cerebellar hemisphere are also stable.3.Stable chronic small vessel ischemic disease.
