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 10: 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
