The mediastinum comprises the area between the lungs and outside of the heart and great vessels. This can be the site of abnormalities of a congenital nature, or benign or malignant growths. Evaluation and treatment of these findings often begins with a biopsy which is typically completed in a minimally invasive outpatient procedure. Definitive treatment may also be completed with a minimal approach, but at time requires more extensive surgery.

Mediastinal abnormalities evaluated and treated may involve the following:

  • Thymus gland
  • Thyroid
  • Lymphoma
  • Germ cell tumors
  • Bronchogenic cysts
  • Esophageal disease


Abnormalities of the mediastinum are often evaluated via mediastinoscopy which involves passing a scope just below the breastbone in order to obtain a biopsy of an abnormal tissue. This is completed as an outpatient procedure with quick recovery.
