Name that Lesion

Alright, folks, it's time for another installment of name that lesion. (Ok, so maybe it's the first, can't remember.) 
Today in Neuroscience we had two hours of lecture on various neuroimaging techniques. One of the techniques described was digital subtraction angiography. Basically you take a regular x-ray, inject contrast media, and then take another x-ray. A computer digitally subtracts everything that is not filled with contrast, so you end up with a picture of only the cerebral arteries. The following example was shown in class:

Can you name that lesion? Be specific! (Vessel, suspected patient signs/symptoms)
Answers will be announced in a couple of days, as well as after-intervention pictures. No prizes other than self-satisfaction.
Update: This entry has been promoted to a "sticky" post until I get some more entries. Answer will be revealed on Monday.

Motor deficits, including facial paresis
Dysarthria and speech impairment
Vertigo, nausea, and vomiting
Headache
Visual disturbances
Altered consciousness
whatever Carsten says, ou are right … it’s a basilar occlusion, the syndrom , if the patient survives is calles locked - in syndrome
Actually I did go to that lecture… And I recall someone suggesting basilar, and the professor telling them they were wrong. My opinion: looks basilar to me, and basically I scoured the net for a pic proving it was not, because that’s what I heard in lecture.
Screw it, Cathie - Congratulations, you won the contest! Your prize? Making a medical student look like an idiot.
