ABSTRACT
INTRODUCTION:
Symptoms encompassing sensorineural hearing loss, tinnitus and vertigo occur in many diseases of various origin. The diagnostics in such cases is especially difficult and often requires interdisciplinary cooperation. Despite of that many cases remain unexplained. MATERIAL ANDMETHOD:
The two cases with above mentioned symptoms (52 year-old woman and 46 year-old man) with differentiated clinical course were presented. The woman for one year experienced left sided, extreme tinnitus with paroxysmal vertigo and dizziness. The man with sudden monolateral hearing loss and tinnitus that disappeared after corticosteroid therapy, complained about recurrence of fluctuating hearing loss and tinnitus accompanied by chronic instability. The diagnostics of hearing and balance organs was performed (pure tone audiometry, impedance audiometry, DPOAE, ABR, ENG) complemented with computed tomography and Nuclear Resonance.RESULTS:
Female patient presented bilateral mild sensorineural hearing loss, more intensive on the left side, male patient right sided sensorineural hearing loss in the frequencies from 250 to 1500 Hz. The elongation of some peak values in ABR test (with bilaterally proper otoacoustic emissions) as well as partial canal paresis on the hearing loss side suggested primary diagnosis of neoplasmatic process. It was an indication to perform radiological diagnostics. The radiologic findings revealed the contact of vestibulo-cochlear nerve with the loop of cerebellar inferior anterior artery within the internal acoustic canal.CONCLUSIONS:
The course of the disease and diagnostic tests do not provide characteristic data that let diagnose neuro-vascular conflict. One has to be aware of such possibility in patients with intensive vertigo and dizziness that do not improve after treatment when other causes do not justify the symptoms.
