Tumors within the nerve canaliculi initially present with unilateral sensorineural hearing loss, unilateral tinnitus, or disequilibrium (vertigo is rare, on account of the slow growth of neuromas). Speech discrimination out of proportion to hearing loss, difficulty talking on the telephone are frequent accompaniments. Tumors extending into the CPA will likely present with disequilibrium or ataxia depending on the amount of extension on the brainstem. With brainstem extension, midfacial and corneal hypesthesia, hydrocephalus, and other cranial neuropathies become more prevalent. For example, involvement of CN V from a<unk>  mass lesion often results in loss of the ipsilateral (same side of the body) corneal reflex (involuntary blink). Patients with larger tumours can develop Bruns nystagmus ('dancing eyes') due to compression of the flocculi.
