Central type lung cancer with obstructive atelectasis and obstructive inflammation accompanied with metastases in the left pulmonary portal and mediastinal lymph nodes as well as multiple bone metastases were evidenced by positron emission tomography-CT (PET-CT) scan [Figure 1]b.{Figure 1}
Chest positron emission tomography/computed tomography (CT) showed enlargement of the right hilar and mediastinal lymph node, uneven enhancement when scanning reinforcement, considering TB; multiple patch and consolidation in the right upper and middle lobe, and considering obstructive atelectasis; small amount of the right pleural effusion and pericardial effusion.
Pulmonary atelectasis is characterized by a state of collapsed and nonaerated region of the lung parenchyma resulting from parenchymal compression (nonobstructive atelectasis) or bronchial obstruction (obstructive atelectasis).
