The differential diagnosis of cerebello-pontine angle lesions. A multidisciplinary approach with special emphasis on the brainstem auditory evoked potential.
92 patients thought to have a cerebello-pontine angle tumour on initial presentation were studied prospectively using standard neuro-otological techniques, brainstem evoked potential recording with a variety of montages, middle latency auditory evoked potentials and CT scanning. 64 patients had a tumour, 40 of which were acoustic neuromas. By analysing the data from all disciplines it has been possible to delineate clusters of variables that are of value in the differential diagnosis of cerebello-pontine angle lesions.
