case_images: The cardiac ultrasound examination disclosed a substantial accumulation of pericardial effusion characterized by fibrous streak-like echoes and large patchy hyperechoic echoes detected within the effusion (Figure 1).
case_images: CTA and CT 3D reconstruction: (A) RAA (indicated by the orange arrow), RAA tumor neck (indicated by the white arrow), thrombus (indicated by the yellow arrow); (B) RAA (indicated by the white arrow).

case_images: An RAA with thrombosis was not ruled out (Figure 2), along with bilateral pneumonic changes.

case_images: A follow-up cardiac ultrasound revealed a hypoechoic mass detected in the right atrium and right atrioventricular sulcus, which was soft and measured approximately 2.36 x 1.24 cm, and a subrounded moderate intensity mass echo was detected within it, which was reduced in size compared to the previous one and measured approximately 0.7 x 0.5 cm (Figure 3).
