Female, 76 years old, with apparent focal gyral thickening in the high convexity right posterior frontal region on a prior CT from 2014. The suspected area of cortical thickening seen on prior CT along the high right frontal vertex appears to reflect slight crowding of otherwise normal-appearing cerebral gyri. There is no differential signal intensity or pathologic enhancement to suggest an underlying mass lesion.Elsewhere, moderately extensive scattered patchy foci of T2 hyperintensity are seen within the white matter of the cerebral hemispheres without edema or mass effect. A small chronic appearing focus of encephalomalacia is seen within the superior left cerebellum. No restricted diffusion is seen. No pathologic parenchymal or extra-axial enhancement is detected. The ventricles are normal in size and morphology. No evidence of acute intracranial hemorrhage or any abnormal extra axial fluid collection is seen.
1.The suspected area of cortical thickening seen on prior CT along the high right frontal vertex appears to represent slight crowding of normal cerebral gyri, likely an anatomic variation.2.No intracranial mass or any other acute intracranial findings are seen. There is evidence of moderately advanced chronic microvascular ischemic disease, as well as a small chronic infarct of the left superior cerebellum.
