Figure 4

Comparison between pulmonary angiography and computed tomography image. (a) Left segmental pulmonary angiography shows abrupt tapering of the arterial branch (arrow), which indicates retrograde flow from the bronchial to the pulmonary artery. (b) Contrast-enhanced coronal computed tomography image shows the aneurysm (arrow) and the parent artery of the aneurysm (arrowhead). The parent artery corresponds to the abrupt tapering of the arterial branch, which was seen in the left segmental pulmonary angiography.
