Laparoscopic Surgery for a Non-Communicating Rudimentary Horn Diagnosed in the Puerperium: Case Report

Abstract

  A non-communicating rudimentary horn with a unicornuate uterus is a rare Müllerian anomaly. We present a case of a 32-year-old postpartum woman who previously underwent a right salpingo-oophorectomy for a cystic teratoma via laparoscopy at age 29; one month postpartum, she experienced right lower abdominal pain. Transvaginal ultrasonography and magnetic resonance imaging (MRI) suggested a left unicornuate uterus and a right rudimentary horn with hematometra. The MRI also suggested that the horn was attached with filmy adhesions to the left lower uterine segment; no urinary tract malformations were detected. Laparoscopic removal of the rudimentary horn was performed using a bipolar scalpel for dissection. A morcellator was used to extirpate the specimen and no complications occurred. The MRI imaging and laparoscopic surgery were useful for the diagnosis and treatment of a non-communicating rudimentary horn.
