Abstract:
Bronchial artery aneurysm (BAA) is a rare but increasingly recognized condition due to advances in imaging. We report two cases of BAA in patients with long-standing pulmonary hypertension. Case 1 is a 30-year-old man with idiopathic peripheral pulmonary artery stenosis diagnosed at age 23. He developed a slightly dilated bronchial artery, which later enlarged, leading to bronchial artery embolization. Case 2 is a 30-year-old woman with pulmonary arterial hypertension diagnosed at age 3. Multiple BAAs were identified at age 24, and progressive enlargement was observed at age 28. Due to lesion complexity, she remains under careful observation.
