ABSTRACT
Background and Objectives:   To report the clinical features of six patients diagnosed with cases of inferior vestibular neuritis based on abnormal vestibular evoked myogenic potential (VEMP) responses with normal caloric test results.
Materials and Methods:  
We retrospectively reviewed 62 patients presenting with dizziness. All patients underwent a battery of audiovestibular testing, including hearing tests, caloric test and VEMP test.
Results:  
Six patients were diagnosed as inferior vestibular neuritis. All patients presented with acute onset of prolonged vertigo. The pure tone audiograms and caloric test results were normal. VEMP response was absent unilaterally, and normal in the contralateral ear.
Conclusion:  
Inferior vestibular neuritis should be considered in patients presenting with acute vertigo, but normal caloric responses. Comprehensive vestibular testing including VEMP is necessary.
Keywords: Vertigo; Vestibular neuritis; Vestibular function test
