a The CT scan showed bronchiectatic consolidation with air bronchogram formation involving the anterior segment of the upper lobe of the right lung with volume loss. Right deviation of the trachea was also demonstrated. Axial (b) and sagittal (c) CT scans showing bronchiectasis in the right upper lobe. The axial CT image also revealed compression of the bronchus of the right upper lobe (arrow).

A coronal computed tomography (CT; fig. 1a) showed bronchiectatic consolidation with air bronchogram formation involving the anterior segment of the upper lobe of the right lung with a 70% loss of volume. Axial, sagittal and coronal oblique CT scans showed bronchiectasis in the right upper lobe (fig. 1b, 1c) and a poststenotic dilatation of the right pulmonary artery with a diameter of 32 mm (fig. 2a).
Axial (a) and coronal oblique (b) CT scans revealed a compression of the superior vena cava (SVC) between an ascending aortic aneurysm (AAA) and the dilated right pulmonary artery (PA). c Volume-rendered 3D CT angiography showed an aneurysmatic ascending aorta (AAA), right pulmonary artery kinking, poststenotic dilatation of the right pulmonary artery (PA), and compression of the superior vena cava. 3D CT angiography also revealed a dilatation of the proximal superior vena cava (SVC).

The CT scan also revealed compression of the superior vena cava between an ascending aortic aneurysm and the dilated right pulmonary artery (fig. 2a, 2b). A volume-rendered three-dimensional (3D) CT angiography image showed an aneurysmal ascending aorta, right pulmonary artery kinking, poststenotic dilatation of the right pulmonary artery, and compression of the superior vena cava (fig. 2c).
