Example case of right-sided renal tumor with a level II IVC thrombus in a 53-year-old female patient. A) B-mode imaging showed solid hypoechoic thrombus in the RRV and IVC. B) CEUS scan showed more lasting, homogeneous, complete marked enhancement of the tumor thrombus in the RRV and IVC. There was adjacent liver washout at 1 min 50s post-injection. C) B-mode imaging showed a formed vessel in the tumor thrombus of the IVC (arrows).
