Figure 1 Thoracic computed tomography scan showed a mass in the upper lobe of the right lung with invasion of the mediastinal pleura and ipsilateral mediastinal lymphadenopathy.

Figure 2 Chest X-ray performed at the second patient’s admission showing the right upper lobe lung tumor, and nodular parenchymal infiltrates in the left upper lobe lung with a small right pleural effusion.

Figure 3 Thoracic computed tomography scan showing a primitive tumor with widespread thin-walled cysts and nodules throughout the lungs but most prominent at the left lung. There were also a small right apical pneumothorax and a small bilateral pleural effusion.
