Pseudothrombosis due to blood-contrast level in the infrarenal vena cava.

Filling defects within the inferior vena cava (IVC) are common findings on computed tomography (CT); nevertheless, a majority of these defects are attributed to artifacts. The documentation pertaining to pseudothrombosis specifically affecting the infrarenal vena cava is notably insufficient in current literature. The aim of this study is to present a case demonstrating a blood-contrast level in the infrarenal vena cava, resembling an intraluminal filling defect.
