The surgical treatment of large malignant thymomas of the anterior mediastinum is associated with a high risk. Recently, a patient with a large malignant thymoma of the anterior mediastinum was treated with surgery, and the outcome is satisfactory. The diagnosis of such tumors is mostly based on the chest X-ray and CT scans, as well as magnetic resonance imaging (MRI). Surgical treatment is the main effective treatment, and should be performed as soon as possible.
