ABSTRACT
Sudden sensorineural Hearing Loss with Vertigo (SHLV) is characteristic of sudden onset vertigo and unilateral hearing loss, due to acute and profound deterioration in a vestibular and cochlear system. It is relatively easy to determine the lesion side in SHLV, because the patient will complain of unilateral hearing loss. But, it might not beapplicable to vestibular neuritis case, and several vestibular function tests may be helpful in deciding the lesion side. We have recently encountered a patient with SHLV whose caloric and SHA did not match with the lesion side. We speculated that the uncompensated dynamic defect and imbalance of the cerebellar clamping has been implicated in this lab finding. Although the exact mechanism of this curious finding cannot be explained by this single case report, we should consider that one could make a mistake to determine the involved site just only by lab finding in vestibular neuritis.
