Neuropathology Flashcard Deck - 10 Cards
Flashcard 1: What is the term for infarcted tissue in the basal ganglia or internal capsule caused by occlusion of a lenticulostriate artery?
Answer: lacunar infarct
Flashcard 2: epidural hematoma
Answer: rupture of middle meningeal artery; fracture of temporal bone
Extra: rapid arterial bleeding lucid interval followed by decreased LOC; CN 3 palsy, increased ICP CT: biconvex, hyperdense blood; does not cross sutures; may cross falx, tentorium
Flashcard 3: central pontine myelinolysis
Answer: often iatrogenic; caused by rapid correction of hyponatremia
Extra: massive axonal demyelination of pontine white matter tracts acute paralysis, dysarthria, dysphagia, diplopia, loss of consciousness; +/- locked-in syndrome T2 MRI: increased signal in central pons
Flashcard 4: subdural hematoma
Answer:
Extra: slow venous bleeding via rupture of bridging veins decreased LOC, increased ICP CT: crescent shaped, hyperdense blood; midline shift; may cross sutures; does not cross falx, tentorium
brain atrophy elderly, alcoholics
Flashcard 5: subarachnoid hemorrhage
Answer:
Extra: rapid arterial bleeding after rupture of aneurysm "worst headache of my life", decreased LOC, increased ICP bloody or yellow CSF CT: blood conforms to shape of gyri, pools in cisterns
nimodipine for late-onset vasospasm vasospasm 2-3 days later, potential for rebleed
Flashcard 6: intraparenchymal hemorrhage
Answer:
Extra: CT: smudgy, patchy blood within parenchyma; typically in basal ganglia and internal capsule
HTN, amyloidosis, vasculitis, neoplasm
