Anomalous vascular loops in close relations to vestibular cochlear nerve complex as possible cause of tinnitus



Anomalous vascular loops are seen in close relation to vestibulo-cochlear nerve complex on either side at the exit zone (CISS seq uence). Vestibulo-cochlear nerves on either side are normal in course and caliber.

Inner ear anatomy is well defined with normal apical, middle and basal turns on both sides.

All three semicircular canals are normally visualized.
The saccule and vestibule are normally visualized.

Bilateral trigeminal nerves are normal in course and calibre with a normal course at the origin and in the region of the Meckel's ca ve on either side.

Bilateral mastoid air sinuses are normal.

IMPRESSION MR FINDINGS ARE SUGGESTIVE OF ANOMALOUS VASCULAR
LOOP AT THE EXIT ZONE OF VESTIBULO-COCHLEAR NERVE COMPLEX ON EITHER SIDE.
