Neurovascular contact types between the AICA and the cochleovestibular nerve. A, A type I neurovascular contact shows no neurovascular contact (arrow). B, A type II neurovascular contact shows contact (arrow) between the AICA and the cochleovestibular nerve without angulation/indentation of the nerve. C, A type III neurovascular contact shows angulation/indentation (arrow) of the cochleovestibular nerve by the AICA loop.
