Figure 1. Patient no. 2. A 47-year-old female patient was admitted to hospital with complaints of chronic cough and dyspnea. Thorax radiography and CT images revealed right-sided arcus aorta with tracheal compression. Spirometry showed a normal flow-volume curve.
Figure 2. Patient no. 3. A 58-year-old male patient was admitted to hospital with complaints of cough and dyspnea. Thorax radiography and CT images showed right-sided arcus aorta with tracheal compression (arrows on Figure 1A-C). The diameter of trachea is seen normal above the aortic arch. But the diameter of trachea is seen significantly narrowed at the same level of arcus aorta due to compression (arrows on Figure 1D).
Figure 3. Patient no. 4. A 63-year-old man was admitted to hospital with dyspnea. Chest radiography showed that the infiltration and shadow of arcus aorta is seen on the right side of mediastinum. The right-sided arcus aorta was confirmed with thorax CT. Pulmonary function test revealed the obstruction.
Figure 4. Patient no. 5. A 24-year-old man suffered from dyspnea and cough, especially with exercise. Thorax radiography and CT images showed right-sided arcus aorta with tracheal compression. Marked compression of the trachea is seen on thoracic CT images (arrows on Figure 4A-C). Pulmonary function test showed the plateau on flow-volume curves throughout exhalation and inhalation (arrows on Figure 4C).
Figure 5. Patient no. 6. A 78-year-old man presented with lung cancer and COPD. Thorax radiography and CT images showed right-sided arcus aorta and pulmonary mass.
