[Bilateral acoustic neurinomas (neurofibromatosis 2)].

Type 2 neurofibromatosis is a rare genetic condition, with an autosomal (dominant) inheritance and a prevalence of 1/50.000 inhabitants, characterized by bilateral acoustic neuromas. We present here a 16-year-old patient with a greater growth of the right-sided neuroma. A review of the literature, regarding incidence, clinical presentation, diagnostic clues and treatment is also included.
