Abstract

Background. Bronchial artery aneurysm (BAA), especially mediastinal BAA is very rare and difficult to diagnose with conventional chest CT. However, recent advances in image processing has enabled us to diagnose mediastinal BAA. Case. A 67-year-old woman was referred to our hospital for hemoptysis. A chest plain CT showed bronchiectasis in the left lower lobe and tumor-like lesion in the mediastinum. Bronchoscopy showed bleeding from the left basal bronchus, so we diagnosed bleeding due to bronchiectasis and planned to perform bronchial artery embolization (BAE). Chest 3DCT reconstructed from dynamic CT prior to BAE revealed the left BAA shaped like a hanging bell, and hyperplastic left bronchial arteries dilating and winding toward the left lower lobe. We performed embolization of BAA with coil following BAE. After successful BAE and BAA embolization, she had no recurrent hemoptysis. Conclusion. Mediastinal BAA is very rare, and 47% (32/68) of the reported cases is presented as rupture of aneurysm with mortality of 6.3% (2/32). Therefore, it is very important to examine for BAA by means of 3DCT actively in patients suspected of aneurysm.
