Mediastinal Tumors are also called as Neoplasms and neoplasms are defined as abnormal growths of tissue. They develop in mediastinum which is the area in the middle of the chest that lies between the sternum and spinal column.

Mediastinal tumors develop in one of the three areas of the mediastinum: the anterior, the middle, or the posterior. These tumors are very rare, children develop them in the back of the mediastinum that is often benign and noncancerous. Adults are more likely to develop them in the front of the mediastinum that is typically malignant.


There are different types of mediastinal tumors and there cause depends on where they form in the mediastinum.

In the front, they can be caused by:

  • Lymphoma
  • Thymoma and thymic cyst
  • Thyroid mass mediastinal

In the middle, they can be caused by:

  • Bronchogenic Cyst
  • Lymphadenopathy
  • Pericardial cyst
  • Thyroid mass mediastinal
  • Tracheal tumors
  • Vascular complications

In the back, they can be caused by:

  • Extramedullary hematopoiesis
  • Lymphadenopathy mediastinal
  • Neuroenteric cyst mediastinal
  • Neurogenic neoplasm mediastinal


Mediastinal tumors don’t show any symptoms. They are found during a chest X-ray. Sometimes symptoms develop that is because the tumor is pushing or surrounding organs. Symptoms include:

  • A cough
  • Shortness of breath
  • Chest pain
  • Fever
  • Night Sweats
  • Coughing up blood
  • Weight loss
  • Swollen lymph nodes
  • Respiratory blockage
  • Hoarseness


  • chest X-ray
  • CT scan
  • MRI
  • A mediastinoscopy with biopsy


Surgery is done to remove the tumor and after that the doctor uses chemotherapy or radiation therapy to destroy remaining cancer cells.
