Diagnosis and Treatment of the Primary Malignant Meningioma in Mediastinum: A Case Report

Abstract: Primary ectopic meningioma is rare and usually limited to the head and neck region. Until now its occurrence in the mediastinum has not been reported in the literature searched on Medline using the keywords meningioma and mediastinum. We report here a case of primary mediastinal malignant meningioma which was treated by surgical resection and additionally followed by radiotherapy. The clinical features, treatment, pathological findings, and prognosis are analyzed and the literature based on ectopic meningioma is reviewed.
