This is a 34 y/o woman who over the past 6 months developed a clumsy right hand, loss of vision in her right peripheral field and slowing of her thinking. During the past few weeks there had been some episodes of bladder urgency with some incontinence. On exam, the right pupil was very slow to react to bright light from a flashlight. She did not see as well in her right visual field. The right side of her face was weak. The right arm did not feel a pin as well as the left arm.
This study demonstrated a large saccular aneurysm off the proximal intracranial left ICA. This aneurysm is compressing the top of the left brainstem. This part of the brainstem carries the impulses to and from the right side of the body (face, arm and leg).
