Anterior mediastinal mass: lymphoma

Case contributed by A.Prof Frank Gaillard

Patient Data

Age: Adult
Gender: Male

Chest x-ray

Frontal chest x-ray demonstrates a large soft tissue density on the right side. It obliterates the normal silhouette of the SVC and right heart border. Hilar vessels can be seen through the mass. The rest of the lungs and the pleura appear unremarkable. 


Chest x-ray

Lateral chest x-ray confirms the mass to be arising anteriorly.

Hilum overly sign - annotated

The ability to visualise pulmonary vessels through the mass implies that it is located either anterior or posterior to the hilum, but not at the hilum. This is known as the hilum overlay sign. 

Case Discussion

This x-ray elegantly demonstrates the features of an anterior mediastinal mass.
