The term mediastinal mass, or mediastinal tumor, describes a growth located in the space within the chest that’s surrounded by the breastbone, lungs and spine (the mediastinum). The mediastinum contains various organs and other body parts, including:
- The aorta
- The esophagus
- The heart
- Lymph nodes
- The thymus
- The trachea
Mediastinal masses can be benign (noncancerous) or malignant (cancerous). There are various types of these masses, including lymphomas and thymomas, among many others.
Mediastinal Mass Symptoms
Mediastinal masses can cause symptoms if they exert pressure on the surrounding body parts. These symptoms may include:
- Night sweats
- Chest pain
- A feeling of fullness within the chest
- Coughing (sometimes coughing up blood)
- Shortness of breath
- Swelling or tenderness within the lymph nodes
- Eye issues that affect one side of the face, including eyelid drooping and pupil shrinkage
- Unexplained weight loss
Although some individuals with mediastinal masses experience symptoms like these, a large percentage (nearly 40%) never experience any symptoms at all. In many of those cases, physicians discover the mediastinal masses when conducting tests for unrelated reasons.
Mediastinal Mass Causes & Risk Factors
Mediastinal masses have a number of potential causes. For example, lymphoma (Hodgkin or non-Hodgkin) can cause masses to form within the mediastinum. Less commonly, masses can develop from rare conditions like extramedullary haematopoiesis.
Mediastinal masses are relatively rare. Although mediastinal masses can develop at any age, they’re most commonly diagnosed in patients between 30 and 50 years old. In a child, the tumor is more likely to be benign (noncancerous) and located at the back of the mediastinum. In an adult, however, the tumor is more likely to be malignant (cancerous) and located in the front of the mediastinum.
Mediastinal Mass Diagnosis
In addition to performing a physical examination, physicians may use the following tests to diagnose a mediastinal mass:
- Blood tests
- Endoscopic procedures, including bronchoscopies, esophagoscopies and mediastinoscopies
- Imaging tests, including computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, ultrasounds and X-rays
Mediastinal Mass Treatment
The methods used to treat mediastinal masses will vary from one patient to another depending on a number of factors, including the type of tumor present and where it’s located within the mediastinum. Potential treatments may include:
- Radiation therapy
It’s important to note that many benign (noncancerous) mediastinal masses need to be promptly treated, since these tumors can compress the adjacent organs and other bodily structures, leading to serious complications.
