Figure 3 Computed tomography arteriography. A: Computed tomography (CT) arteriography revealed a tortuous artery ascending from the right inferior phrenic artery that arose directly from the aorta (arrows); B: CT arteriography demonstrated several tortuous arteries arising from the left subclavian artery that descended obliquely along the right main bronchus (arrows); C: A collateral right bronchial artery (BA) arising from the inferior phrenic artery. Right inferior phrenic arteriography showed an abnormal tortuous artery (arrows); D: Ectopic BAs arising from the left subclavian artery. Left subclavian arteriography showed abnormal tortuous arteries arising from a root of the left subclavian artery (arrows).
