Aims of this study are 1) to evaluate radiological characteristics of the anterior inferior cerebellar artery (AICA) using three-dimensional Fourier Transformation Constructive Interference in Steady State (3D-FT CISS) MR imaging, and 2) to investigate the relationship between types of AICA and auditory or vestibular symptom. Materials and Methods：This is a retrospective study. Forty-five adult patients, who presented with auditory symptom and/ or vestibular symptom of unknown etiology at an ENT hospital from April 2010 to August 2011, were studied. Using 3D-FT CISS images, AICA course was identified in all the patients (90 ears). The relationship was investigated between types of the AICA loop and vestibulocochlear symptom. Results：According to Chavda’s classification, 55 type I loops, 24 type II loops and11 type III loops of the AICA were observed. Only type III loops show a statistically significant association with ipsilateral hearing loss and tinnitus (p=0.0001). According to Shelton’s classification, 14 class A courses, 52 class B, 18 class C and 6 class D were observed. However, any sigificant relationship was not found between cochleovestublar symptoms and AICA types of class A through D. Conclusion：A significant relationship was found between AICA loop and auditory symptom, when it extends more than 50% of the length of IAC. In these patients, neurovascular compression of vestibulocochlear nerve could be considered as a possible cause of hearing deterioration and tinnitus.
