Abstract

Recently, a novel influenza A (H1N1) has been recognized as the cause of a worldwide respiratory infection outbreak. Although the symptoms of a novel influenza A (H1N1) are usually mild, the disease can cause severe illness and death. A complication of novel influenza A (H1N1) is pneumomediastinum, a rarely reported condition. We report a case of influenza A (H1N1) complicating pneumomediastinum with subcutaneous emphysema, which had initially presented with blood tinged sputum and chest pain. In addition, we demonstrate bronchoalveolar lavage in influenza A (H1N1).

  Figure 1 Chest radiograph on admission showed pneumomediastinum and peribronchial haziness in both lungs (A~C).

• 

  Figure 2 Neck radiograph on admission showed subcutaneous emphysema, neck and upper thorax (A, B).

  Figure 3 High resolution computed tomography of chest on admission. (A) Showed subcutaneous inter-, intra-muscular emphysema in scan covered lower neck. (B~D) Peribronchial ground grass opacity in both lower lobe, right middle lobe, superior and inferior lingular segment of left upper lobe, posterior segment of right upper lobe.

  Figure 4 High resolution computed tomography of chest after 2 weeks. (A) Disappeared subcutaneous inter-, intra-muscular emphysema in scan covered lower neck. (B~D) Disappeared pneumomediastinum and improved peribronchial ground grass opacity in both lower lobe, right middle lobe, superior and inferior lingular segment of left upper lobe, posterior segment of right upper lobe.
