A 53-year-old male patient presented with chronic cough and expectoration as the main symptoms. Chest computed tomography (CT) revealed consolidation and cavity formation in the right upper lobe (Figure 1A). A mediastinal abscess was observed on the posterior wall of the tracheal carina (Figure 1B). Flexible bronchoscopy showed no abnormal findings in the tracheal mucosa (Figure 2A).

A 52 year old man presented with a 1 day history of cough and hemoptysis. The total volume of expectorated blood was approximately 200 mL. Due to the large volume of bleeding and oxygen saturation decreasing, the patient underwent emergent bronchial artery embolization under Digital Subtraction Angiography (DSA).
