Abstract
A 56-year-old male patient was admitted to our hospital with respiratory distress persisting for half a month as the chief complaint. The patient developed dyspnea following a heated argument, and his symptoms progressively worsened over time. Upon admission, he was unable to tolerate light physical activity due to shallow breathing. Vital signs revealed a blood pressure of 103/68 mmHg, heart rate of 85 bpm, and oxygen saturation level of 87% with 3 L/min of oxygen inhalation. Pulmonary computed tomography (CT) displayed massive pleural effusion on the left side, while computed tomography angiography (CTA) of the pulmonary identified a large pulmonary arteriovenous fistula in the lower lobe of the left lung and a small arteriovenous fistula in the upper lobe of the right lung (Figure 1). Diagnostic thoracentesis suggested hemorrhagic pleural effusion (pleural fluid routine: total erythrocyte count: 42,200 106/L).
