A 35-year-old woman underwent an abdominal MR venogram 5 days post dilatation and curettage for an intrauterine fetal death at 25 weeks. Coronal images from a post-contrast venous phase fat saturated T1 sequence of the abdomen demonstrates the post-partum uterus (a, curved arrow), with marked dilatation of the right (b, arrow) and left (c, arrow) gonadal veins with central filling defects consistent with bilateral gonadal vein thrombosis. The thrombus extends up to the juxtarenal IVC (c, curved arrow). Axial image from a T1 post-contrast venous phase fat saturated T1 sequence of the abdomen (d) demonstrates the expanded gonadal veins bilaterally with central filling defects
