[Pantopaque cisternography in diagnosis of acustic neuromas (author's transl)].

In 6 out of 37 patients, examined by pantopaque cisternography the suspect of a acustic neuroma could be strengthened. All of these tumors showed growth beyond the internal auditory meatus. Smaller intrameatal tumors were not found. The indication for cisternography were made almost according to the demands from Fisch and Wegmüller, therefore it is asked, wether it should not be better to follow the methods of Valvassori who sometimes performes cisternography based on audiometric findings alone. As results of our own experience and similar cases reported elsewhere, this seems justified. Because of the small amount of contrast medium used the side-effects of Pantopaque-cisternography are practically nil.
