Audiological findings in a case of cerebellar angioreticuloma.

The aetiology of neurosensorial damage with unilateral hearing loss and/or tinnitus and dizziness can often be difficult to determine because they may be caused wide variety of pathologic processes and a variety of diagnostic tests are needed in initial evaluation. In this paper, the authors describe, the techniques and indications of neuroimaging for evaluation of auditory symptoms. Auditory brainstem response (ABR) testing is still the choice when condition is suspected. We present a study of one patient with unilateral tinnitus, with no significant hearing loss and normal ABR: the patient underwent MRI of the district brain and the internal auditory channel (AIC) that showed the presence of a rare intracranial neoplasm, namely cerebellar angioreticuloma.
