23. A 48-year-old man with severe uncontrolled systemic hypertension develops a headache and vomiting. Two hours later he has left-sided weakness followed rapidly by loss of consciousness. He dies shortly after admission to the emergency department. A section of his brain as seen at autopsy is shown. The most likely mechanism of the lesion shown is hemorrhage from which of the following?
A. Bridging vein
B. Congenital arteriovenous malformation
C. Intracerebral vein
D. Lenticulostriate artery
E. Saccular aneurysm of the anterior cerebral artery
I know that in hypertension lenticulostriate vessels can turn weak, thus causing an hemorrage, but how we're gonna differentiate from a sacular aneurysm (no in the case of this question because involves the ACA and is not the brain location marked by the image), but if we dont have an image, how differentiate a saccular (berry aneurysm) from a bauchart aneurysm clinically?
