The Role of Pulmonary Veins in Cancer Progression from a Computed Tomography Viewpoint

Figure 1

Central parenchymal pulmonary lesions. The patient is a 63-year-old man with renal cell carcinoma who underwent targeted therapy. He felt dyspnea. Chest X-rays were taken at time (a) and 1 month later (b), which shows the rapid progression of the left upper lung mass. A CT scan (c) shows the bulging left superior vein and 1 month later (d) reveals the lung parenchymal mass located outside the left superior pulmonary veins.
