The chest X-ray showed total atelectasis of the left lung (Figure 1), and the thoracic CT-scan revealed a mass of the left hemithorax, which probably originated in the mediastinum and extended to the whole left pleural space (Figure 2).
Preoperative CT-scan of the chest revealing the mass compressing the mediastinal vessels and airway.

Specifically, the MRI confirmed a round, non-homogeneous, well circumscribed mass of a 12 cm diameter, exerting compression on the mediastinum great vessels and the left hilar structures (vessels and airway) (Figure 3).
Postoperative X-ray of the chest after total resection of the teratoma, showing re-expansion of the left lung.
