[Use of computer tomography in the diagnosis of syndromes of the cerebellopontile angle].
The contribution of the scanner, among the different radiological examinations performed for suspected cerebellopontine angle syndromes, was assessed in 101 cases, of which 76 were neurinomas. Direct signs, with evaluation of the different characteristics of the tumors, were studied together with indirect signs. Results demonstrated that computed tomography was a simple, reliable, and low-risk examination, and that it could avoid more traumatic radiological investigations in the majority of cases. Furthermore, when associated with spinal canal air injections it provides confirmation of diagnosis of suspected intraspinal tumors. As a complementary clinical or paraclinical examination (audiometry, E.N.G., acoustic reflexes, evoked potentials, conventional radiographs, tomography, among others) it can establish the precise diagnosis of a cerebellopontine angle tumor and should be performed in all suspected cases.
