case_images: (A) Transthoracic echocardiography revealed a large echogenic mass in the right atrium (red arrow), (B) Contrast echocardiography showed that the mass in the Fig. 1A does not enhance with intravenous contrast agent, indicating that this mass may be a bland thrombus (red arrow), (C) Inferior vena cava appears distended and occluded with echogenic material and no signs of flow (between the red arrows) in the transthoracic echocardiogram.

case_images: Echocardiogram revealed a large echogenic mass in the right atrial cavity (Fig. 1A, red arrow) which did not enhance with intravenous echo contrast agent (Fig. 1B, red arrow). Inferior vena cava (IVC) appeared distended and occluded by echogenic material with no signs of flow (Fig. 1C, between red arrows).
case_images: (A) Computed tomography pulmonary angiography before contrast enhancement showed that the mass extends from inferior vena cava to the right atrium, (B) Computed tomography pulmonary angiography after contrast enhancement revealed that this mass enhances with contrast agent, indicating that this mass may be a tumor thrombus, (C) Sagittal view showing the tumor thrombus extending from inferior vena cava to the right atrium, (D) Coronal view showing the tumor thrombus extending from inferior vena cava to the right atrium.

case_images: Computed Tomography (CT) showed PVTT, as well as a distended and occluded IVC by a mass that extended to the right atrium (Fig. 2A, C, D) and enhanced with intravenous contrast agent (Fig. 2B, C, D), and thus the mass was considered as a tumor thrombus. CT Pulmonary Angiography (CTPA) was negative for pulmonary embolism.
