case_images: Using the CT coronal scan to simulate bronchoscopy, no obstruction signs in the larynx, trachea, or main bronchi were found (Figure 2).

case_images: An emergency gastrointestinal examination (Figure 3A) showed that there was patchy erythema near the corner of the stomach with a smooth surface and suspected vascular malformation. The pathology identified mild chronic inflammation of the mucosal tissue (Figures 3B,C).
case_images: Fibrobronchoscopy of the left (A-C) and right (D-F) lobes of the bronchus.

case_images: By conducting a thorough bronchoscopy (Figures 4A-F), we found a smooth mucosal protrusion in the opening of the right lower lobe. It was suspected of being a new formation, and bleeding after contact was obvious (Figure 4F).
case_images: Bronchial angiography (A) before and (B) after embolism.

case_images: The angiogram showed that the bilateral bronchial arteries showed distortion; the distal end was disordered, blurred, and irregularly stained; and more contrast agents showed signs of spillage (Figure 5A). Re-examination angiography showed satisfactory embolization of the bilateral bronchial arteries (Figure 5B).
