Vascular loop at IAC

A 45 y o male with right side pulsatile tinnitus. 

Thin axial T2 images at the level of IAC show a vessel probably the right AICA forming a loop around right side 7th-8th nerve complex.
Vascular loops in the internal auditory canal may generate pulsatile tinnitus.
However significance to this finding to be given in proper clinical context only and the diagnosis of vascular compression syndrome should not be based solely on imaging findings.
