type of intracranial hemorrhage?
primary brain parenchymal hemorrhage
intraparenchymal hemorrhage
most important predisposing factor of primary Brian parenchymal hemorrhage?
hypertension

hyaline arteriolosclerosis
this is an intracranial considered non traumatic; hypertensive hemorrhage
intraparenchymal hemorrhage
this can happen as a result of intraparenchymal hemorrhage that causes deposition of amyloidogenic peptides in the walls of medium and small caliber meningeal and cortical vessels
what does this cause?
what causes this?
cerebral amyloid angiopathy
weakened vascular wall
gene polymorphism in apolipoprotein E
what are the examples of subarachnoid hemorrhage

where do saccular aneurysm occur?
bifurcations
what are the two mechanisms possible that cause saccular aneurysms?
