ANEURYSM OF THE POSTERIOR INFERIOR CEREBELLAR ARTERY

I have not talked to my ENT who ordered a MRA of the neck. The right PICA has a high origin and arises from the basilar. The anterior and inferior cerebellar arteries are normal bilaterally' Negative for aneurysm or intracranial stenosis. Negative for vascular loop within internal auditory canals. The anterior circulation is normal as well. What does it mean to say the PICA has high orign and arises from the basilar/ Anything to worry about? Thanks Debbie Coleman
