| description |
The Video Head Impulse Test (vHIT) is used to assess vestibular function. It has been shown to be valuable in patients with Vestibular Schwannoma (VS).
We present a case of a 64-year-old male with a 6mm VS in the left internal acoustic canal, detected incidentally on a brain Magnetic Resonance Imaging. The patient denied experiencing any vestibular or auditory symptoms. Physical examination revealed mild left sensorineural hypoacusis, and a positive left head impulse test. The vHIT showed a normal vestibulo-ocular reflex (VOR) gain value in all semicircular canals (SCCs), despite the presence of corrective saccades (CSs) while testing the left lateral and posterior SCCs.
The vHIT is a valuable tool for evaluating vestibular function. In patients with normal VOR gain values, subtle deficits in the SCCs can be detected through the presence of CSs, indicating the importance of incorporating vHIT into routine diagnostic evaluations of patients with vestibular disorders.
