FLAIR images demonstrate posterior predominant areas of high signal, more severe
on the right, involving the white matter. There is involvement of the right
occipital cortex with associated mass effect.
Abnormal white matter signal is seen on the T2 coronal image, with no restricted
diffusion on DWI. Low signal is seen in the white matter on axial T1, with patchy
enhancement of the posterior temporal and occipital white matter.
FLAIR images document near complete resolution of the previous signal abnormalities.
