Imaging appearances in case 1. (A) Enhanced chest computed tomography (CT) showing the pulmonary thromboembolism (arrow) in right inferior pulmonary artery and bilateral pleural effusion. (B) Iodine contrast esophagogram confirmed the bronchoesophageal fistula. (C) Coronal magnetic resonance imaging (MRI) showed the mediastinal soft tissue shadows (arrow) surrounded the left main bronchus.

CT showed pulmonary thromboembolism in his right upper and inferior pulmonary artery, bilateral pleural effusion, pulmonary infection, multiple enlarged mediastinal lymph nodes and soft tissue shadows that surrounded his left main bronchus (Figure 1A and C). CT also revealed frontal lobe hemorrhage. A bronchoesophageal fistula on his left main bronchus was later discovered by iodine contrast esophagogram in response to persistent dry cough, and then he received nasal jejunal nutrition (Figure 1B).
CT images of case 1 in September (A) and November (B). The enlarged mediastinal lymph node (arrow) decreased after antituberculosis therapy.
