Varices of the round ligament mimicking an inguinal hernia--an important differential diagnosis during pregnancy.

Pregnancy is a recognised risk factor for the development of inguinal hernias due to an increase in intra-abdominal pressure. Whilst often managed conservatively until after the pregnancy, if the hernia presents acutely as a painful or tender groin lump, urgent or emergency repair may be required. Many clinicians rely heavily on clinical examination alone in order to diagnose the presence of such a hernia. In pregnancy, however, in order to prevent unnecessary surgery, the use of ultrasound has a more important role to play in reaching this diagnosis. We report a cautionary case that highlights the need for ultrasound evaluation of all painful groin lumps in pregnant women prior to considering surgery.
