Presentation
Worsening cough of unknown duration.
Patient Data



Chest X-ray demonstrates a large anterior mediastinal mass that appears to be projecting over the right hilum. Lateral X-ray confirms anterior mediastinal mass with obliteration of retrosternal airspace.
Case Discussion
Given the patient's presenting symptoms and imaging findings of an anterior mediastinal mass on chest X-ray, a non-exhaustive differential for this case could include a thymic neoplasm, thyroid neoplasm, germ cell tumour (such as a teratoma or seminoma), or lymphoma. These pathologies are known to frequently occur in the anterior mediastinal compartment. This patient was eventually found to have a biopsy-proven thymoma necessitating surgical resection.
