Stereotactic radiosurgery has been proposed as the first line treatment for @entity5 and has been particularly advocated in cases of @entity8605 ( @entity13755 ) with bilateral acoustic nerve @entity5 . We present the case of a 22-year-old male with @entity13755 and bilateral acoustic nerve @entity5 . He underwent an uncomplicated excision of the larger, left sided lesion. Histology showed a benign @entity5513 with no atypical features. One year later he underwent stereotactic radiosurgery (Gamma Knife 1500 cGy) to the right sided lesion. After @entity5 had reduced in size and undergone central necrosis. However, 2 years later MRI of the brain revealed a dramatic increase in the size of the right sided @entity5 , with considerable brain stem compression. The @entity1 subsequently died. This highly unusual case highlights the need for careful clinical and radiological follow up. in @entity1 with @entity5 , regardless of the treatment method employed.
