Résumé
We report a case of inguinal hernia that contained the entire uterus and both adnexa, presenting with an irreducible soft mass in the left groin and asymmetric labia majora, in a 2-month-old, full-term girl who visited the emergency department. Ultrasonography was performed immediately, and urgent surgical repair was performed without complications. Although inguinal hernia is a common surgical disease, it is rare that the hernia contains the uterus with its adnexa, and presents as a mass of the labia majora. Unlike the bowel herniation, the entity can be complicated by strangulation of the ovary, leading to infertility. To preserve fertility, rapid and accurate diagnosis using ultrasonography should be considered in an infant with an irreducible inguinal mass and asymmetric labia majora.
