case_images: Chest CT (Figure 2) demonstrated a large anterior mediastinal mass (13 cm x 6 cm) compressing the SVC, right pleural effusion, and subcarinal and pericardiac lymphadenopathy.
case_images: Positron emission tomography (PET) scan showing a hypermetabolic mediastinal mass (see arrows).

case_images: fig3
case_images: Positron emission tomography (PET) scan confirmed a hypermetabolic mediastinal mass extending to the subcarinal region and inferiorly to diaphragmatic surface along the right side of the heart with maximum standardized uptake value of 6.5 (Figure 3).
case_images: The tumor cells (see arrows) exhibit features of small-cell carcinoma: nuclear molding, high nuclear-to-cytoplasm ratio, and fine chromatin pattern/"salt and pepper" nuclei. H and E (hematoxylin and eosin) staining.
