Patient who presented with alterered mental status and a recent syncopal event. NCCT (A) demonstrated an ill-defined low-density lesion in the left cerebellar hemisphere (curved arrow on A, B, and C), as well as other lesions within the left basal ganglia (not shown). MR demonstrated hyperintense signal within this region on T2WI (B). On coronal contrast-enhanced T1WI (C), a ring-enhancement was noted within this region; a single intralesional susceptibility signal focus was identified (D).
