I need advice. 
I have undergone extensive CT and MRI scans. My pulsatile tinnitus is on the left side. The scans revealed three findings. First, the Anterior Inferior Cerebellar Artery (AICA) is compressing the vestibular and cochlear nerves on the left side. The neuroradiologist believes this is the most likely cause of the pulsatile tinnitus, but none of the three surgeons I have seen agree.
Meanwhile, on the right side of my head, the scans show sigmoid sinus dehiscence and a very large arachnoid granulation in the transverse sinus. All the doctors think that the granulation and dehiscence are likely causing the pulsatile tinnitus, but they hesitate when they realize these issues are on the right side, while my symptoms are on the left.
I am feeling really down about this situation. I am struggling to cope with the uncertainty and the inability to get a clear diagnosis.
Can anyone help make sense of this?
