Abstract Objective: Analyze vestibular aqueduct MRI T2WI features of a group of patients affected with large vestibular aqueduct syndrome(LVAS). Methods: From Jan. 2011 to Dec. 2013, 150 patients affected LVAS had been diagnosed by means of temporal bone CT and brain MRI in our hospital. We analyzed MRI T2WI features of vestibular aqueduct area in all 297 ears. Results: Based on vestibular aqueduct T2WI features, endolymphatic duct and endolymphatic sac were divided into 2 types. Among all endolymphatic ducts and endolymphatic sacs, 10.8% were type Ⅰ with only hypointensity, while the rest 89.2% were type Ⅱ with both hypointensity and hyperintensity. Conclusion: There are different imaging features in vestibular aqueduct on MRI T2WI for LVAS.
