title: Cerebellopontine angle pilocytic astrocytoma mimicking acoustic schwannoma.
abstract: We describe a case of pilocytic astrocytoma of the cerebellum mimicking an acoustic schwannoma. The tumour protruded into the porus acusticus and enlarged the internal auditory meatus, which is a quite unusual characteristic of glial tumours.
