Mediastinal Mass
A mediastinal mass is an abnormal growth in the central part of the chest between the lungs.
When to get help quickly: Urgent review is more important if breathing is affected, swallowing becomes difficult, chest pain is severe, or there are signs that the mass is compressing important structures.
Common symptoms
Some mediastinal masses cause no symptoms, while others can lead to cough, chest discomfort, shortness of breath, swelling, or pressure-related symptoms depending on size and position.
When imaging helps
Imaging helps define exactly where the mass is, what structures are nearby, whether it looks cystic or solid, and whether biopsy planning is needed.
What radiology does
Chest CT and MRI help define where the mass is, what structures it affects, and whether biopsy planning is needed.
What usually happens next
Management depends on the cause and may include monitoring, biopsy, surgery, oncology care, or specialist chest evaluation.
