Pathology of Hemorrhagic Diseases of the CNS Flashcards
This disease is due to grossly enlarged arteries and veins due to fibromuscular thickening. Symptoms such as, headaches, seizures, and neurological deficits may appear before hemorrhage.
Atreriovenous malformation
This type of aneurysm is caused by a congenital defect at branch sites, often at the Circle of Willis. It has a higher incidence in patients with polycystic kidney disease, Ehlers-Danlos, and Marfan Syndrome.
Berry Aneurysm
Ruptured cerebral aneurysms most commonly present where?
Subarachnoid space
What is Duret’s hemorrhage?
Inflammation, edema, and herniation of the cerebellum causing secondary hemorrhage in the pons
What are some potential causes of nontraumatic intracerebral hemorrhage?
Hypertension, vasculature malformation, amyloid angiography, drug use
What is a slit hemorrhage?
Rupture of small vessels that produce a slit-like cavity surrounded by liquid
What brain structures are most at risk for hypertensive hemorrhage?
Putamen, thalamus, cerebellum, pons, lobar white matter
What sinus is most often indicated in dural sinus thrombosis?
Superior sagittal sinus
Cavities called lacunar infarcts, slit hemorrhages, and encephalopathy are most associated with what nontraumatic cause of intracerebral hemorrhage?
Systemic hypertension
Thrombosis of this sinus often has infectious etiology.
Cavernous sius
