CTICasesIatrogenic Bronchial Artery Pseudoaneurysm
Imaging findings
Initial chest radiograph shows fullness in the right hilum and adjacent lung opacities. Contrast-enhanced CT demonstrates a hyperdense contrast blush arising from a right bronchial artery, adjacent to a ground-glass lung nodule. Catheter angiography confirms a partially thrombosed, active bronchial artery pseudoaneurysm. Post-intervention CT demonstrates successful coil embolization of the pseudoaneurysm with no further contrast filling.
Key takeaways
Bronchial artery pseudoaneurysm is a rare, life-threatening iatrogenic complication that can occur after invasive procedures such as transbronchial biopsy or endobronchial ultrasound-guided needle aspiration of lymph nodes. It should be considered in any post-procedural patient presenting with hemoptysis. Catheter-directed coil embolization is highly effective for definitive management.
