Neurologic examination showed left-sided hyperactive deep tendon reflexes, Achilles clonus, dysmetria, ataxia to the left and plantar reflex with extensor response on the left. Video head impulse test and cervical evoked myogenic potential tests were performed. Vestibular hypofunction was present on the left side.
