The Schwannoma of the Upper Mediastinum Originating From Nervus Vagus: An Unusual Case Report

Abstract

Schwannoma is a neurogenic tumor, usually with posterior mediastinum localization arising from the intercostal nerves and is primarily benign. It is also known that rarely, it may show the malignant transformation. It is usually asymptomatic and incidentally emerges as a solitary mass on plain radiography. A 49-year-old male patient was admitted to our hospital with a chronic cough complaint. A well-circumscribed mass of 6 × 5 × 3 cm in size, detected in the right para-tracheal space on computed tomography, was excised by right thoracotomy. Histopathological diagnosis has been reported as schwannoma. Schwannomas with thorax localization originating from different neural structures are quite rare. We present a rare case of schwannoma with successful management in this article. © 2025 Elsevier B.V., All rights reserved.
