title: Cerebellopontine angle tumors.
abstract: Acoustic neuromas account for approximately 80 to 90 per cent of cerebellopontine angle tumors. Useful imaging studies include (1) high-resolution CT of the internal auditory canals using extended scale and "bone algorithm" techniques, (2) infusion study of the cerebellopontine cisterns, (3) gaseous or opaque CT cisternography, and (4) MRI.
