Intercostal artery pseudoaneurysm in pulmonary TB: a rare ca
Pulmonary tuberculosis (TB) is one of the common causes of life-threatening hemoptysis, particularly in developing countries. Bronchial and pulmonary arteries are the major source of hemoptysis in pulmonary TB. Intercostal artery pseudoaneurysm as a cause of hemoptysis in pulmonary TB is extremely rare, with only a few reported cases.

Published in the journal Lung India, the authors describe a case of intercostal artery pseudoaneurysm in a patient of pulmonary TB, presenting as massive hemoptysis.

CT bronchial angiography (CTBA) revealed a contrast-filled outpouching in a left upper lobe cavity. Catheter angiography revealed a pseudoaneurysm arising from one of the left intercostal arteries, which was managed subsequently by endovascular embolization.

Major takeaway:-
- Pseudoaneurysm from visceral arteries is an extremely rare but important cause of massive hemoptysis in pulmonary TB, which if not managed promptly may prove fatal.
