Figure 1. Results of computed tomography (CT) and endoscopic ultrasonography (EUS). A: no abnormal lesions were found by CT scan where EUS found the metastasis lesion (arrows); B: a low-echo lesion in mediastinum was found and suspicious of metastasis using EUS; C: no enhancement in the lesion was found after intravenous injection of SonoVue; D: malignant lesion was supported by cell samples from EUS-FNA, showing large variations in size and chromatin unevenly distributed with rough granules (magnification, ×100).
