Noninvasive diagnosis of bronchial artery aneurysm using dual-source computed tomography angiography.

Bronchial artery aneurysm is a rare entity, detected in less than 1% of all patients undergoing selective bronchial arteriograms. Approximately 50 cases have been reported so far. Computed tomography (CT) reports of mediastinal bronchial artery aneurysms are rare. We report a case of a bronchial artery aneurysm in an 84-year-old male patient, which had been misdiagnosed as lung cancer for 6 years.
