Figure 1: MRI brain. Axial T2 WI (a) shows a single conglomerate lesion of 2 cysts (thick arrow and hairpin-arrow) with extensive perilesional edema on the right side of the tegmentum of the midbrain. The core of the larger cyst is hyperintense on T2 WI (a) and hypointense on FLAIR (b) images suggesting signal suppression. Scolex is seen as eccentric dot-like hypointensity (thin arrow in a) on T2 WI (a) and as hyperintensity (thin arrow in b) on FLAIR (b) images. Axial post gadolinium T1 WI (c) shows peripheral enhancement of the lesion, MR spectroscopy (d) shows lipid peak at short TE (arrowhead)
