A 40-year-old female graduate student
had an excruciating headache. When she
looked in the mirror, she noticed that her
eyelid was drooping; when she lifted the
eyelid, she saw that her eyeball was looking
down and out and her pupil was huge.
She complained of both blurred and double
vision. An magnetic resonance angiogram
scan showed an aneurysm of the cerebral
arterial circle. Which artery gives rise to the
offending aneurysm?
