18-F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) showing uptake of FDG at the right hilar and mediastinal lymph nodes (A). Chest enhanced CT showing the low-density area inside the mediastinal lymph node, indicative of necrosis (B). The CT at 24 days after EBUS-TBNA showing no evidence of enlargement of mediastinal nodes or cardiac effusion (C). Chest CT obtained 30 days after EBUS-TBNA showing pericardial effusion (D), and enlargement of mediastinal lymph nodes with increased fat tissue concentration (E).

Chest computed tomography (CT) showed a tumor in the upper lobe of the right lung, and enlargement of multiple mediastinal and right hilar lymph nodes (Fig. 1A and B). The lung tumor and mediastinal lymph nodes were found to be necrotic (Fig. 1B); the necrotic areas were avoided under ultrasonographic guidance during aspiration. The chest CT scan revealed further enlargement of the lymph nodes with pericardial effusion (Fig. 1D and E). Six days before admission, a CT scan for planning radiation therapy revealed no complications from EBUS-TBNA (Fig. 1C).
