A diagnosis of distended right ovarian vein with an intraluminal thrombosis was made and the patient was taken up for contrast Multidetector computerized tomography (MDCT).
80-90% of POVT occur in the right ovarian vein. The right ovarian vein terminates in the inferior vena cava at an acute angle and the left ovarian vein terminates in the left renal vein at right angles.
Regarding the hydroureter, it is believed to be due, in part, to the commonly occurring dextro torsion of the enlarged uterus, which causes compression of the right ovarian vein and right ureter as they cross the pelvic rim.
CT revealed a left ovarian vein filling defect, which extended into the pelvis with multiple filling defects in the left and right ovarian veins. The veins were edematous and tortuous as well as enlarged.
