Unicornuate Uterus With a Non-communicating Rudimentary Uterine Horn Treated via Laparoscopic Resection With Preservation of Both Ovaries and Fallopian Tubes: A Case Report and Review of the Literature.

A unicornuate uterus with a non-communicating rudimentary horn is a variant of the unicornuate uterus that is associated with gynecologic and obstetric complications. Dysmenorrhea, infertility, recurrent abortion, and acute or chronic pelvic pain are the most common presenting complaints. We report a case of a 21-year-old single girl who presented with dysmenorrhea since she began menarche. Magnetic resonance imaging and three-dimensional ultrasonography were performed, revealing a unicornuate uterus with a left-sided, non-communicating rudimentary horn. The patient underwent laparoscopic resection of the left non-communicating rudimentary horn. The presence of a left-sided, non-communicating rudimentary horn measuring 4.0 x 2.0 x 2.0 cm with secretory endometrium, which tested negative for malignancy, was confirmed via histopathologic investigation. The patient became asymptomatic after follow-up at the gynecologic clinic. The early diagnosis of a unicornuate uterus with a non-communicating rudimentary horn is crucial to prevent any complications. A thorough preoperative assessment is an extremely vital step to decrease the rate of intraoperative complications. High laparoscopic skill levels are important for the effective treatment of a unicornuate uterus with a non-communicating rudimentary horn.
