Figure 4.

Patient with bladder carcinoma and recent onset priapism. Axial TOF sequence (A) shows lack of flow related enhancement within IVC (white arrow) with anterior abdominal wall collaterals (yellow arrows). Coronal reformatted MIP image (B) of TOF sequence shows flow within bilateral iliac veins with paraspinal collaterals (arrow) and non-visualization of IVC. Contrast venography image (C) shows a lack of enhancement within IVC with thrombus filling its lumen. No contrast enhancement was seen within the thrombus on arterial phase image (D). TOF, time of flight; IVC, inferior vena cava.
