Atelectasis is collapse of lung tissue with loss of volume. Patients may have dyspnea or respiratory failure if atelectasis is extensive. They may also develop pneumonia. Pleuritic chest pain may be present with certain causes of atelectasis. Diagnosis is by chest x-ray.
In atelectasis, air does not leak into the pleural cavity (the area between the lungs and chest wall). Pneumothorax is the presence of air in the pleural cavity as a result of trauma or disease. Pneumothorax ultimately causes atelectasis due to compression or collapse of lung parenchyma.
