title: [2 cases of neurinoma of the mastoidal portion of the facial nerve: diagnostic contribution of MRI].
abstract: The authors report 2 cases of patients presenting a neurinoma of the 3rd portion of the facial nerve. In the 2 cases, the surgical observations correlated perfectly with the results of the radiological examinations (scanner and MRI). The clinical and paraclinical presentation of this rare tumor is recalled, emphasizing the additional contribution of imaging techniques: the scanner is indeed indispensable for evaluating the osseous destructions on the intrapetrous trajectory of the facial nerve, whereas MRI (in particular with injections of gadolinium) evaluates the exact tumoral limits as best as possible.
