A focal area of gyral swelling and T2 and FLAIR hyperintensity at the left parietotemporal region with reduced representation of the posterior ascending branch of the left Sylvian fissure. In the same area, weakly hyperintense signal in DWI and marked nodular leptomeningeal enhancement are appreciated. Focal meningeal involvement is clearly demonstrated.
Pencil-thin line of hyperintensity T2 and FLAIR surrounds ventricles. Some T2 and FLAIR hyperintense punctate foci in the sub-cortical and deep white-matter is also appreciated.
