(A, B) Chest CT scan showing an irregular soft tissue density mass (yellow arrow) on the right side of the anterior mediastinum that compressed the adjacent right lung (blue arrow), accompanied by pleural effusion (white arrow). (C, D) Contrast-enhanced chest CT scan showing that the mass had moderately uneven enhancement, which invaded the right lung (blue arrow), and the mediastinal lymph nodes were enlarged (red arrow). (E, F) The coronal multiplanar reconstruction images clearly delineated the irregular and uneven density mass on the right side of the anterior mediastinum with invasion of the superior vena cava (red arrow), pericardium (black arrow) and right lung (blue arrow).
