Intrathoracic vagus nerve tumors: a report of two cases and review of the literature.

We have observed 741 mediastinal tumors during the past 25 years. Among these tumors, two intrathoracic vagal tumors were found; one bilateral neurofibrosarcoma and one neurilemmoma. To date, 49 intrathoracic vagal tumors have been reported in the literature, and the neurofibrosarcoma described here is the fourth malignant vagal tumor reported.
