Abstract

A bronchial artery aneurysm is a rare condition, which needs optimal treatment due to the possibility of a life-threatening hemorrhage by rupture. The surgical removal of the aneurysm is the standard treatment. However, there are a few reports of coil embolization with a transcatheter. A 69 year-old man was referred for a further evaluation of a mass in the right hilum on chest radiography. He denied any respiratory symptoms. A chest CT scan showed a 3 x 3 x 4.5 cm sized vascular mass with strong contrast enhancement on the right hilar area that originated from the bronchial artery. On the angiogram, the bronchial artery originated from the descending thoracic aorta at the T8 level. A bronchial artery aneurysm was catheterized selectively. and embolized successfully with a coil. After coil embolization, the selective bronchial arteriography confirmed complete occlusion. We report this case of bronchial aneurysm that was treated successfully with coil embolization.

Figure

  • Figure 1 Chest roentgenogram on admission. About 3.5 cm sized, well-defined, mass like opacity is noted in Rt. hilar area (A). About 3 × 3 × 4.5cm sized, well-enhancing mass is noted in right hilar area, supplied by thoracic aorta and drained into azygos and SVC junction(B).

  • Figure 2 Aortogram demonstrates two right bronchial arteries (arrows) and bronchial artery aneurysm (arrowheads)(A). Even though first embolization was done, bronchial artery aneurysm was still enhanced on chest CT scan(B). Selective right bronchial arteriogram shows bronchio-pulmonary artery fistula (arrowheads) in the bronchial aneurysm(C). Right subclavian arteriogram demonstrates aneurysm of the aberrant bronchial arteries arising from right internal mammanry artery and thyrocervical trunk (D).

  • Figure 3 After second embolization was done, bronchial artery aneurysm was not enhanced on chest CT scan.
