title: Cerebello-pontine angle paraganglioma simulating an acoustic neurinoma.
abstract: An unusual case of paraganglioma arising from the internal auditory meatus and growing into the cerebello-pontine angle is reported. Clinical features, pre-operative radiological appearances and intra-operative findings were indistinguishable from those of an acoustic neurinoma. However, the paraganglionic nature of the tumour was confirmed by the electron microscopic evidence of neurosecretory features.
