Recurrent T-Cell Lymphoma
Imaging findings
Chest radiograph shows a subtle right-sided hilar/mediastinal contour abnormality (bump) that is not visible on the lateral view. CT confirms a small, recurrent anterior mediastinal T-cell lymphoma/leukemia mass.
Key takeaways
Subtle mediastinal masses can be difficult to detect on chest radiographs, particularly when they project close to vascular structures on the frontal view and are invisible on the lateral view. High clinical suspicion should prompt CT.
