 There is a large area of encephalomalacia involving the left superior and middle temporal gyri with mild gliosis of the surrounding parenchyma. There is also a small area of cortical FLAIR signal abnormality in the left inferior frontal lobe. Additionally, scattered foci of subcortical white matter FLAIR and T2 hyperintensity are noted. The gyri and parenchymal volume otherwise appear normal. There is no diffusion weighted abnormality to suggest acute infarct. There is no abnormality noted on susceptibility weighted images. There are no foci of abnormal enhancement within the brain. The ventricles are normal in size and configuration. There are no masses, mass effect or midline shift. There are no extraaxial fluid collections. The major vessels of the brain enhance normally. The paranasal sinuses and mastoid air cells are clear.
1.Encephalomalacia in the left temporal lobe with additional scattered areas of signal abnormality in the left frontal lobe and subcortical white matter, likely from prior ischemic events.2.No specific findings to suggest a degenerative etiology for dementia.
