[The value of CT in the diagnosis of tumours of the cerebello-pontine angle. Comparison of various radiological, clinical and otological examination].

An attempt has been made to define the role of CT in the diagnosis of cerebello-pontine angle tumours; 190 patients with this suspected diagnosis were examined by CT (including intravenous contrast enhancement and CT air cisternography) as well as other radiological, otological, neurological and audiometric investigations. Amongst these methods, CT is of most value. A knowledge of the variations of the internal auditory meatus and measurements of the porus acousticus are essential for evaluating the computer tomographic appearances.
