Disease | Pathology |
Hypertension | degeneration of intima media →fragmentation of arterial smooth muscle → lipohyalinosis, fibrinoid necrosis of subendothelium, microaneurysms, focal dilatations in arteriols |
Primary CNS vasculitis | transmural inflammation, vessel wall injury |
Cerebral amyloid angiopathy | amyloid fibril accumulation in small-medium sized arteries |
Cavmals / Angiomas | irregular venous-type channels lined by flat endothelium surrounded by scant smooth muscle |
AVM | abnormally high flow often causes ectatic remodeling of the veins draining the AVM or of the arteries feeding it |
Hypoxic ischemic encephalopathy | pseudolaminar necrosis |
