Abstract
BackgroundVestibular neuritis (VN) is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost.Case presentationsWe describe three patients with symptoms suggestive of VN, but normal calorics. All 3 had unilateral loss of vestibular evoked myogenic potential. A slight, asymptomatic position dependent nystagmus, with the pathological ear down, was observed.ConclusionWe believe that these patients suffer from pure inferior nerve vestibular neuritis.

Halmagyi et al [3] presented two cases of acute vertigo with normal calorics but with pathological vestibular evoked myogenic potential (VEMP) and other findings indicating a lesion of the inferior part of the vestibular nerve, with sparing of the superior vestibular nerve
Summary
Vestibular neuritis (VN) is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. Patients who present with similar symptoms but normal caloric test results are commonly assumed to suffer from a lesion of the central nervous system [2]. Halmagyi et al [3] presented two cases of acute vertigo with normal calorics but with pathological vestibular evoked myogenic potential (VEMP) and other findings indicating a lesion of the inferior part of the vestibular nerve, with sparing of the superior vestibular nerve.
