Surgical Treatment of Mediastinal Schwannoma Showing Malignant Potentiality on Chest Magnetic Resonance Imaging Study : A Case Report

Nerogenic tumor of various histologic types may arise in the posterior mediastinum. Mediastinal schwannoma is a frequent paraspinal neurogenic tumor, but malignant mediastinal schwannoma is rare tumor which is derived from Schwann cells. Although there are some reports dealing with approach for screening patients with symptoms suggesting malignancy and the imaging criteria for distinguishing malignant from benign schwannoma but the results are not clearly defined. We present a case of hugh mediastinal schwannoma which was taken for malignancy in imaging studies because of its invasiveness.
