Imaging techniques. a) Chest x-ray: Massive pleural effusion occupying most of the left hemithorax with evident displacement of the mediastinum to the right (blue arrow). b) Chest computed tomography: The left lung is atelectatic and compressed by massive pleural effusion (red arrow). The mediastinum and the trachea are severely displaced to the right. A few lymph nodes can be seen, deeply in the left axilla. Additionally, some paratracheal lymph nodes can be observed (yellow arrow). c) Chest computed tomography: A 3,5 × 4,5 cm peripheral lesion, on the left upper lobe, with relative abnormal contour and extension into the surrounding parenchyma. The tumor is in contact to the splanchnic pleura and approached the parietal pleura, possibly invading it (green arrow). d) Digital mammography: Diffuse asymmetrical density in the subalveolar region and the upper outer quadrant of the left breast.
