Sagittal non-contrast
CT brain shows two hyperdense nodular deep white matter lesions located in the right corona radiata region and in the left frontoparietal transition, both associated with an extensive hypoattenuating area surrounding them and that may correspond to a vasogenic oedema. The mass effect is more pronounced in the right where it causes a mild right lateral ventricle compression; bilateral mild sulcal effacement. No midline shift. It is also notated a small not well-defined hypoattenuating area in the left cerebral peduncle.
