Intrathoracic schwannoma originating from intrathoracic vagus nerve

Abstract

In differential diagnosis of posterior mediastinal mass should be included the intrathoracic vagus nerve tumor. Surgical excision of intrathoracic vagus nerve schwannoma is associated with a low recurrence rate and excellent long-term results.

Keywords: mediastinum; neurilemmoma; schwannoma; vagus nerve.
