Three lung CT scans during hospitalization. A. Before diagnosis: anterior superior mediastinal mass with a small amount of pleural effusion; B. Second visit to our hospital: anterior superior mediastinal mass with massive pleural effusion on the right side, incomplete expansion of the right lung; C. After the patient receiving VICLP chemotherapy and antibiotics treatment, the anterior superior mediastinal mass became smaller than before, and the right lung was re-expanded. The right lung inflammation and right pleural effusion decreased (Note: the red arrow shows mass; the blue arrow shows pleural effusion location).
