The chest radiograph documented right lower pneumonia (Figure 1).
CTA demonstrated that BA1 originated from the thoracic aorta to the left at the level of the upper margin of T5 and entered the right hilum above the bifurcation of the trachea. BA2 arose from the right side of the thoracic aorta at T6 and passed up to the right and then down to the right hilum, with a widening of the diameter (2 mm) of the primary and middle tubes.

Bronchial artery 2 arose from the right side of the thoracic aorta at T6 and passed up to the right and then down to the right hilum with a 2 mm widening of the primary and middle tube diameters (Figure 2).
Angiography showed that the right lower bronchial artery had the same origin as the left bronchial artery, and the vascular lumen was dilated. The right lower lung branches were disorganized, with a small amount of light staining in the parenchymal phase.

The right lower lung branches were disorganized, with a small amount of light staining in the parenchymal phase (Figure 3).
Aortic angiography showed an ectopic bronchial artery originating from the right renal artery and entering the right lower lung with tortuous and disordered peripheral vessels; the pulmonary artery branch is shown in the arterial stage.

Aortic angiography visualized an ectopic bronchial artery originating from the right renal artery and entering the right lower lung, with tortuous and disordered peripheral vessels, and the pulmonary artery branch was apparent in the arterial phase (Figure 4).
The end of the ectopic bronchial artery is blocked.

In consideration of the presence of a bronchial-pulmonary artery fistula, embolization was performed at the distal end of the vessel (Figure 5), and the subsequent revealed that the artery was occluded at the distal end.
Chest X-ray documented atelectasis in the right lung.

Subsequent chest X-ray documented atelectasis in the right lung (Figure 6).
One day after bronchoscopy, no evidence of atelectasis was found on the chest X-ray.

The chest radiograph did not reveal any evidence of atelectasis on the second day of bronchoscopy (Figure 7).
