Computed tomography pulmonary angiography (CTPA) in (A) axial plane and (B) coronal maximal intensity projection (MIP) demonstrating single left pulmonary artery (yellow arrow) and absent right pulmonary artery. Note the reduced right lung volume. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

CT pulmonary angiogram of the chest was performed showing unilateral absence of the right pulmonary artery with right lung hypoplasia (Fig. 1). CT angiogram of the aorta showed dilated tortuous bronchial artery forming a complex systemic network that supply the right lung (Video 1), with a collateral from a dilated right internal thoracic artery. (Fig. 2).
MIP images from computed tomography angiography (CTA) of the thorax in (A) axial plane showing abnormally dilated and tortuous right bronchial artery (blue arrows) supplying the right lung. (B) Coronal plane of CTA showing right internal thoracic artery (dark blue arrow) supplying the right lung apex.

(A) Right bronchial artery angiogram demonstrating exuberant right bronchial artery and its branches (purple arrow) supplying the right lung parenchyma. (B) Post-embolization angiographic run showing significant reduction of flow of the right bronchial artery.

Post-partum, bronchial artery pulmonary angiography demonstrated a dilated and tortuous right bronchial artery, dilated internal thoracic artery, with an abnormal tortuous branch supplying the right apex (Fig. 3).
