Rationale:
Bronchial artery aneurysm (BAA) is a rare condition, but it can be life-threatening if the aneurysm ruptures. While endovascular therapy is the primary treatment, the selection of embolic material is limited by the tortuous and short aneurysm neck.
Patient Concerns:
We report a huge, suspected ruptured BAA was unexpectedly detected in a 69-year-old man during a routine medical examination.
Diagnoses:
Enhanced chest computed tomography angiography and selective bronchial arteriography both revealed that the BAA was located at the proximal portion of the left bronchial artery It was characterized by a large aneurysm sac and a short, irregularly dilated aneurysm neck.
Interventions:
We successfully occluded the huge BAA using a single amplatzer vascular plug.
Outcomes:
The 6-month computed tomography angiography follow-up scan showed no signs of aneurysm recurrence.
Lessons:
Transcatheter embolization utilizing a single amplatzer vascular plug has proven to be an effective and cost-efficient treatment for BAAs that are characterized by a large aneurysm sac and a short, tortuous, irregularly dilated aneurysm neck.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
