Diagnostic Considerations

When a lesion is identified in the mediastinum, the first task is to determine its location. Because mediastinal seminomas typically occur in the anterior mediastinum, it is essential to rule out other lesions that also commonly occur in this location, including the following:

  • Lymphoma
  • Thymoma
  • Retrosternal goiter
  • Teratoma
  • Metastatic lesion from elsewhere
