Abstract
Bronchial artery-pulmonary artery fistulae are rare vascular malformations most commonly caused by infection. Our case presents a 57-year-old male who presented to the Emergency Department with a symptomatic bronchial artery-pulmonary artery fistula due to cavitating pulmonary tuberculosis (TB). The diagnosis was made with multiphase CT angiography of the thorax (including pulmonary and systemic arterial phases). The patient was brought to interventional radiology for further investigation and management. The left upper lobe bronchial artery-pulmonary artery fistula was successfully identified and treated with endovascular embolization. Bronchial artery-pulmonary artery fistulae can pose a diagnostic and therapeutic challenge. Our case demonstrates endovascular embolization as an effective method of treating symptomatic bronchial artery-pulmonary artery fistulae.
