case_images: Liquefaction of brain parenchyma was noted in several foci [Figure 4].
case_images: (a) Ectatic and fibrous vascular channels without intervening brain parenchyma - black arrows (H and E x400), (b) malformed vascular spaces (blue arrows) with focal calcifications (black arrows) in fibrous wall (H and E x100).
