CT-angiography image showing a bronchial artery aneurysm (white arrow) that arises at the origin of the left bronchial artery and some dilated bronchial arteries (arrowheads), posteriorly and laterally to the trachea (A). Three-dimensional volume-rendering technique (VRT) image depicts the aneurysm (white arrow) and the enlarged bronchial arteries (arrowheads) more clearly (B).

Chest CT angiography was performed and a single bronchial artery aneurysm, 9 mm in diameter, was seen originating from the aortic arch and abutting the posterolateral left wall of the middle-third of the esophagus with hypertrophy of bronchial arteries along their mediastinal course (Figures 1, 2).
Axial CT image (A) and VRT image (B) showing aneurysm (arrow) compression on the posterolateral left wall of the middle-third of the esophagus (star).

In addition, there was a diffuse thickening of the walls of many bronchial branches - without evident bronchiectasis, and "ground glass" opacity in the anterior segment of the right upper lobe suggestive of alveolar hemorrhage (Figure 3).
Axial CT image (A) and VRT image (B) obtained after endovascular embolization, demonstrate a complete occlusion of the aneurysm (arrow) and the disappearance of bronchial artery enlargement.
