From the case: Ovarian vein thrombosis and sigmoid diverticulitis
Abdominal CT-scan (monophasic)
Axial C+ portal venous phase
The sigmoid shows multiple diverticula with infiltration of the surrounding mesenteric fat, findings that are compatible with diverticulitis. On the left lateral side of the sigmoid colon a dilated venous structure is seen with an endoluminal round thrombus. This vein can be followed upward where it is seen to branch from the left renal vein: thrombosis of the left ovarian vein.
