Fig 1 Computed tomography and 18-fluoro-2-deoxy-D-glucose positron emission tomography of a patient with a large mass in the anterior mediastinum. (A) Computed tomography revealed a heterogeneously enhanced anterior mediastinal tumor 78 × 73 mm in size. (B) The initial presentation. The maximum standardized uptake value of the anterior mediastinal tumor was 28.75. (C) An image of the metastatic tumor on the left adrenal grand. The maximum standardized uptake value of the left adrenal tumor was 20.8.

Fig 2 Pathological findings of the anterior mediastinal tumor. (A) Hematoxylin and eosin staining: The proliferation of spindle-like atypical cells was observed. The cellularity was very high (×20). (B) Hematoxylin and eosin staining: Invasion into the mediastinal fat tissue was observed (×4). (C) CD34 staining: The tumor tissue was positive for CD34 (×20). (D) Ki-67 staining: The Ki-67 labeling index of the tumor was 50% to 60% (×20).
