Extracorporeal membrane oxygenation for lung cancer-related life-threatening hypoxia: A case report

Figure 1 Initial chest radiography, chest computed tomography scan, bronchoscopy, and positron emission tomography-computed tomography. A: Chest radiography reveals a mass-like shadow in the right supra-hilar area; B: Chest computed tomography (CT) showing narrowing of the right main bronchus secondary to a mass; C: Bronchoscopy confirms that the right bronchus is almost completely obstructed by a mass; D: Positron emission tomography-CT showing a 5-cm hypermetabolic mass (SUVmax 20.8) in the right upper lobe and hypermetabolic 4R and 2R lymph nodes.

Figure 2 Changes on chest radiography. A: On hospital day 3, chest radiography shows near total atelectasis of the right lung; B: On hospital day 5, atelectasis in the right lung is aggravated; C: On hospital day 16, the near total atelectasis of the right lung has improved, although right upper lobe atelectasis remains; D: On hospital day 19, right upper lobe atelectasis has improved.

Figure 3 Changes on chest computed tomography scan. A: After two cycles of gemcitabine/cisplatin chemotherapy, the size of the right upper lobe mass has decreased; B: After concurrent chemoradiotherapy, the right main bronchus, narrowed by the tumor, has further improved.
