A large enhancing partially-cystic mass is centered at the left frontotemporal lobe and measures 54 x 64 x 73 mm. The nodular mildly hyperdense portions show strong contrast uptake in an area measuring 25 x 18 mm, extending into the left frontal lobe. The lesion exerts mass effect in form of rightward subfalcine herniation and left uncal herniation. There is associated rightward midline shift (displacing the midline by 12 mm), with asymmetric dilatation of the lateral ventricles and findings of transependymal CSF permeation.
