ABSTRACT
Antepartum cases of ovarian vein thrombosis are extremely rare and often misdiagnosed.
A 22-year-old nullipara at 29 weeks' gestation presented with right lower quadrant
pain and fever. Sonography revealed a tubular, hypoechoic mass. At laparo-tomy, a
noninflamed appendix was found and a 2 × 4 cm retroperitoneal mass was palpated near
the right ureter. Postoperative magnetic resonance imaging (MRI) revealed bilateral
thrombosis of the ovarian veins with caval extension. Therapeutic anticoagulation
was achieved, but the patient underwent cesarean delivery 4 days later due to active
labor and malpresentation. Postoperative MRI showed no extension of the thrombi, and
her postpartum course was otherwise unremarkable. MRI is a valuable, noninvasive tool
in the diagnosis of venous thrombi in pregnancy.
