MRI of the brain of our case. The upper row are coronal-enhanced images and the lower row are axial-enhanced images. We can see the ring strengthening lesion in the left lateral ventricle para frontal angle involving the callosum (white → is the strengthening lesion) with central necrosis and perilesional edema. Both MRIs on October 10 and October 28 show progressive enlargement of the lesion with worsening of perilesional edema, and the white △ arrow shows a new lesion in the right lateral ventricle of the right parietal lobe
