Inguinal hernia containing functioning, rudimentary uterine horn and endometriosis

Abstract

Background: Inguinal hernia containing uterus and endometriosis is exceedingly rare. Most inguinal endometriosis is located at an extrapelvic site near the round ligament. We report a case of a patient with inguinal hernia containing rudimentary uterine horn and endometriosis.

Case: A young, nulliparous, regularly menstruating woman manifested right inguinal mass and pain in the mass during menstruation. At 20 years old, she underwent a surgical procedure for right inguinal mass. Postoperative pathology findings demonstrated inguinal endometriosis. Based on the findings of magnetic resonance imaging, a history of inguinal endometriosis, and the occurrence of inguinal pain during menstruation, she was diagnosed as having incarcerated inguinal hernia containing anomalous uterus and endometriosis. A functioning, noncommunicating, rudimentary uterine horn and endometriosis were surgically removed from the hernia sac. Laparoscopy demonstrated intraabdominal unicornuate uterus, but no pelvic endometriosis.

Conclusion: Functioning, incarcerated hernia uterus inguinale may be associated with müllerian abnormality and concomitant occurrence of inguinal endometriosis.
