Ill-defined altered signal intensity lesions in bilateral frontal lobes, splenium of corpus callosum on the left, right globus pallidus and thalamus, midbrain on the right, left temporal lobe, bilateral occipital lobes, and left cerebellar hemisphere. Post-contrast study shows ring enhancement of the lesions in the splenium of the corpus callosum, midbrain, and left cerebellar hemisphere. The rest of the lesions show nodular homogenous enhancement.
Post-contrast FLAIR shows enhancement along sulcal spaces of the left frontotemporal lobe and right frontal lobe, and left Sylvian fissure.
