[Nuclear magnetic resonance diagnosis of tumors of the internal auditory canal and the cerebellopontile angle].

The diagnosis of acoustic neuromas has been continually improving. By means of gas cisternography used additionally, intracanalicular neuromas can be imaged indirectly. However, these procedures lead to a certain degree to both false positive and false negative results. With MRI, as the latest imaging technique, it is always possible to detect early stages of intracanalicular growth. When using a surface coil spatial resolution will be less than 1 mm. Our experience with this imaging technique in the diagnosis of tumours of the inner ear canal and the cerebellopontine angle is discussed and our indications for the use of MRI are presented.
