Round ligament varicosities: a rare cause of groin swelling in pregnancy.

Round ligament varicosities (RLVs) are rare, and only occur in pregnancy. The swelling due to RLVs mimics an inguinal hernia and generally resolves spontaneously after delivery. Distinguishing between varicosities and hernias is critical to avoid unnecessary surgeries on pregnant women. We aimed to determine the significance of RLVs during pregnancy and to review and describe their clinical and sonographic characteristics. All patients were diagnosed by gray scale and color Doppler ultrasonography, managed conservatively, and RLVs regressed spontaneously postpartum.
