[Morbus Menière and acousticus-neurinoma (author's transl)].
It is questionable whether a hydrops endolymphaticus can develop on the basis of an acousticus-neurinoma. Histological evidence is also lacking. The fact that an acousticus-neurinoma can very rarely lead to the classical symptoms of Menière's disease has practical consequences. If a significant decrease in caloric function and an asymmetry in the inner ear ducts exist, a meato-cisternography is indicated. In the meato-cisternogramme typical filling defects are found; but also in 50% of the patients with Menière's disease, certain types of filling defects are seen. This observation suggests that perhaps other pathological processes in the inner ear duct provoke symptoms similar to those of Menière's disease. In our patient material we have indications that isolated intrameatal liquor circulation disturbances and intrameatal angioma are much more often associated with the clinical symptoms of Meniere's disease than an acousticus neurinoma.
