ABSTRACT

Unilateral sensorineural hearing loss and tinnitus are common presenting complaints in patients with cerebellopontine angle tomor. Sudden deafness is an unexpected initial symptom in these patients. Recently, we experienced two cases of cerebellopontine angle tumor with sudden deafness as an initial symptom. Fifty years old male patient complained of an only sudden deafness without tinnitus and dizziness. Forty one years old male complained of sudden deafness with tinnitus. He was also treated by medical therapy in other hospital and improved partially. But, he got worse immediately after discharge. Diagnostic evaluations are based on audiologic examinations and radiologic finding, especially magnetic resonance imaging.

The cerebellopontine tumor can present atypically with sudden deafness as an initial symptom, so we report its characteristics with review of literature.
