    Author: Berrettini S, Ravecca F, Russo F, Bruschini P, Sellari-Franceschini S.
    Journal: J Otolaryngol; 1997 Apr; 26(2):97-103. PubMed ID: 9106084.
    Abstract:
    OBJECTIVE: The most common initial symptoms of the acoustic neuroma are unilateral hearing loss that evolves gradually, tinnitus, and unsteadiness. However, atypical presentations may sometimes occur, more often with a small intracanalicular neuroma or with a large medial neuroma placed in the cerebellopontine angle. RESULTS: In our group of 51 patients suffering from acoustic neuroma, atypical presentations were observed in 9 cases (17.6%). Two patients had normal hearing function but reported tinnitus; two patients reported sudden hearing loss, with partial recovery; two patients had a history of fluctuating hearing loss; two patients reported neurologic symptoms (one reported trigeminal paresthesia and the other had a history of trigeminal paresthesia and recurrent headache); and one patient reported profound hearing loss for many years and the recent onset of unsteadiness. CONCLUSION: Patients with these atypical presentations have to undergo a diagnostic evaluation for acoustic neuroma and must be evaluated with BAEPs and then with gadolinium-enhanced MRI.
