Subsequent brain MRI performed two months later exhibited nodular focal leptomeningeal enhancement overlying the superior cerebellum, interpeduncular cistern, frontal region, superior temporal lobe, periventricular region, near the obex, and in the left internal auditory canal (Figures 1(a) and 1(b)).
