Pulmonary Artery Pseudsoaneurysm due to Mycobacterium Tuberculosis Managed Successfully by Transcatheter Coil Embolization

Pulmonary artery pseudoaneurysm due to mycobacterium tuberculosis is a rare clinical entity. A 29 years old female presented to us with hemoptysis. She was a known case of pulmonary tuberculosis and was on antitubercular treatment. Emergency transcatheter coil embolization of the neck of the sac of pseudoaneurysm arising from the right descending pulmonary artery was done. At 6 months of follow up, the patient was asymptomatic. We are reporting this case due to a rare presentation of pulmonary artery pseudoaneurysm due to mycobacterium tuberculosis and pulmonary artery as an unusual source of hemoptysis instead of the bronchial artery. Learning objectives Pulmonary artery pseudoaneurysm due to Mycobacterium tuberculosis although rare but it's a potential life threatening situation, however early detection and prompt management may prevent fatal complications. Thus, the treating physician should keep this as a differential diagnosis whenever a patients presents with a massive hemoptysis.
