Multiple schwannomas of the bilateral mediastinal vagus nerves.

Multiple schwannomas arising from the mediastinal vagus nerve are very rare, but herein we report a case with such lesions involving the bilateral intrathoracic vagus nerves. A 43-year-old man presented with multiple mediastinal tumors during a check-up. A chest computed tomographic scan revealed multiple lesions that appeared strung together like beads along the right vagus nerve. Three small tumors were also evident on the left side of the esophagus. We performed a complete resection of the bilateral mediastinal tumors through right thoracoscopic surgery. The pathologic diagnosis for each of these tumors was a schwannoma without malignant components.
