case_images: However, echocardiography performed on July 31, 2020, which was recommended owing to chest pain, revealed a 4.97x2.72 cm mass-like echogenicity adhering to the right ventricular free wall (Figure 1).
case_images: Chest computed tomography performed on August 6, 2020, showing a new lesion in the right ventricle near the pulmonary valve.

case_images: Furthermore, chest CT performed on August 6, 2020, demonstrated a new lesion in the right ventricle near the pulmonary valve, and metastasis in the pericardium was ruled out (Figure 2).
case_images: PET scan image of the heart on August 14, 2020, revealing increased FDG uptakes in the right submandibular and mediastinal lymph nodes, bilateral lungs, heart, and pericardium which impress metastases.

case_images: Service for further survey and treatment. Subsequent whole-body PET performed on August 14, 2020 revealed metastases in the right submandibular and mediastinal lymph nodes, bilateral lungs, heart, and pericardium (Figure 3).
case_images: Cardiac magnetic resonance imaging on August 19, 2020, revealing a lobulated and infiltrative enhancing soft tissue mass, mainly located in the anterior wall of the right ventricle.
