Diagnosis usually involves a combination of imaging studies and biopsy. Common diagnostic tools include:
- Chest X-ray: Often the first step in detecting a mediastinal mass. - CT Scan: Provides detailed images of the chest and helps determine the mass's size and location. - MRI: Useful for assessing the involvement of adjacent structures. - Biopsy: A tissue sample is obtained for histological examination to determine the nature of the mass.
