Mediastinal Disease

Mediastinal Treatments

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


Mediastinoscopy is a medical procedure used to investigate and diagnose conditions within the mediastinum, which is the central compartment of the chest located between the lungs. It is typically employed when there is a suspicion of certain diseases or conditions, such as lung cancer, lymphoma, infections, or inflammatory disorders, affecting the structures in this region. It’s a safe and effective procedure, typically performed under general anesthesia. During a mediastinoscopy, we make a small incision at the base of the neck and inserts a thin, flexible tube with a camera, called an endoscope. This enables direct visualization of the mediastinal structures and allows us to obtain tissue samples from the lymph nodes and other areas within the mediastinum. These tissue samples are crucial for accurate diagnosis, staging, and treatment planning, particularly in cases where other diagnostic methods like imaging or biopsies are inconclusive or insufficient.
