Neurilemmomas of the cervical vagus nerve.

Four patients were seen with neurilemmoma which arose in the cervical vagus nerve. Three tumors arose in the upper third of the lateral neck, and the remaining one in the lower third. Lateral neck mass was a prominent symptom in 3 patients, and parapharyngeal mass in the remaining one. The parapharyngeal mass bulged into the oropharynx in the tonsillar and retrotonsillar region and caused mild swallowing difficulty. Complete surgical extirpation by means of intracapsular enucleation was possible in all 4 patients. All patients remained free of disease for periods ranging from 15 to 75 months following surgery. It would appear that an intracapsular enucleation may be advisable for clearance of this kind of tumor.
