case_images: Transthoracic 2-D echocardiography shows about a 3x4 cm-sized mass attached to its apical wall in the right ventricular chamber. LA, left atrium; LV, left ventricle; M, mass; RV, right ventricle.

case_images: Transthoracic and transesophageal 2-D echocardiography showed a large mass tightly attached to its akinetic apical wall in the right ventricular chamber (Figure 1).
case_images: Contrast-enhanced CT (A) and T1-weighted MRI (B) show a large intracardiac mass involving the pericardium and myocardium in the right ventricle (double arrows), and a mass in the right lower lobe of the lung (single arrows). 18F-FDG PET (C) demonstrates that the intracardiac tumor had an intensely increased FDG uptake (double arrows), which is strongly suggestive of malignancy.

case_images: Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a large tumor having involvement of the epicardium and myocardium in the right ventricle, and there was a mass in the right lower lobe of the lung and multiple lymphadenopathies (Figure 2A, 2B). Subsequent FDG PET confirmed that the intracardiac mass had an abnormally increased FDG uptake, which was strongly suggestive of malignancy (Figure 2C).
case_images: The cytologic examination of US-guided percutaneous fine needle aspiration reveals malignant epithelial cell nests, and this was strongly suggestive of squamous cell carcinoma. (Papanicolaou smear, x200)

case_images: The cytologic examination of the percutaneous fine needle aspiration of a lymph node in the anterior mediastinum revealed malignant epithelial cell nests that were strongly suggestive of squamous cell carcinoma (Figure 3).
