Diffuse bilateral symmetrical confluent areas of abnormal signal intensity (high FLAIR and T2) involving the white matter regions bilaterally (deep and sub-cortical). No associated areas of restricted diffusion or significant enhancement in the post-contrast T1WIs. Multiple small areas of high T2 and low T1 signal are noted involving the white matter more noted involving the deep white matter suggestive of cystic changes/dilated Virchow-Robin spaces. Relatively dilated ventricular system with prominent Sylvian fissures and brain cisterns as well as frontoparietal extra-axial CSF spaces. Thickened convolutions of the cerebral cortex especially frontoparietal regions showing loss of normal sulcation.
