Varices in the round ligament are very rare and have only been reported in pregnant women as an inguinal mass normally detected in the third trimester of gestation. B-mode and Doppler color ultrasonography are fundamental tools in the diagnosis, because they make it possible to reach a conclusive diagnosis and to rule out other clinically possible inguinal masses. Given that the treatment is conservative, it is essential for the radiologist to be familiar with this condition and its ultrasonographic characteristics to enable the correct diagnosis and avoid unnecessary surgical exploration.
