Epiploic appendagitis is seen as an ovoid region of fat density with a hyperdense surrounding halo and extensive fat stranding (dotted blue circle).
The IVC is enhanced above the renal arteries due to contrast-enhanced blood flowing out of the kidneys (red arrows) well before blood has had time to reach the legs and pelvis and return via the iliac veins to the infrarenal IVC (green arrow).
On the sagittal image (last image on right), the coeliac trunk (CT), the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) are all well seen. Irregularity of the anterior aortic wall is due to pulsation of the artery during image acquisition.
