A 63-year-old male with chronic hypertension is found unconscious in his living room and brought to the ER. His vital signs on arrival are: blood pressure 210/110, heart rate 77, respiratory rate 22, and oxygen saturation 95% on room air. A head CT reveals intracerebral hemorrhage. Which of the following statements is likely?
* A. Basal ganglia, thalamus and pons are uncommon sites for hypertensive intracerebral hemorrhages
* B. A cerebral angiogram of the patient will reveal Charcot-Bouchard aneurysms
* C. Hypertension is not the likely cause of this patient’s condition
* D. Rupture of a berry aneurysm in the circle of Willis can result in this type of hemorrhage
* E. All of the above

Re: Pathology babbu5508 - 03-18-11 18:46 If a Charcot-Bouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage, which can cause hemorrhagic stroke, typically experienced as a sudden focal paralysis or loss of sensation. In contrast, if a saccular aneurysm ruptures, it will lead to a subarachnoid hemorrhage, typically experienced as an extremely severe headache leading to loss of consciousness.
