 There has been near complete resolution of right frontal/parietal extra-axial collection with minimal residual collection still present measuring up to 3 mm on series 701 image 14 without significant mass effect. There is no acute infarct, mass effect or midline shift. There is mild periventricular and subcortical white matter T2 signal abnormality which is nonspecific, likely representing chronic microvascular ischemic changes. There is mild diffuse volume loss which is slightly asymmetrically prominent in the left frontal and parietal lobe. There is no hydrocephalus. There is mild bilateral maxillary, scattered ethmoid and trace right mastoid mucosal thickening. There is a right frontal/parietal burr hole.
1.Mild chronic microvessel ischemic changes with no acute infarct.2.Near complete resolution with 3-mm thick residual right frontal/parietal extra-axial collection.3.Mild diffuse volume loss which is slightly asymmetrically prominent in the left frontal and parietal lobes.
