A Case Report on a Left Unicornuate Uterus With Communicating Right Rudimentary Horn Associated With Hematometra and Hematosalpinx

Congenital uterine anomalies (CUAs) or Müllerian duct anomalies are rare and can be either complete failure or partial failure in the development of the Mullerian duct, and they have a probability to result in a condition known as the unicornuate uterus. Partial development of one of the horns results in a rudimentary horn, which may be communicating consisting of category II A or noncommunicating consisting of category II B. This report illustrates a rare case of a 23-year-old female, unmarried, nulligravida, who presented to the outpatient department with chief complaints of acute abdominal pain and dysmenorrhea associated with an average menstrual flow. Pelvic ultrasound and magnetic resonance imaging (MRI) confirmed the diagnosis of a left unicornuate uterus with communicating right rudimentary horn associated with hematometra and hematosalpinx. As a treatment option, the surgical intervention mainly involved laparoscopic excision of the rudimentary horn and right salpingectomy that was performed by aspiration of blood from the rudimentary horn of around 25cc. Then, the right hydrosalpinx was removed, followed by right salpingectomy and excision of the rudimentary horn to reduce the risk of ectopic pregnancy having an incidence of 10% for which laparoscopic or robotic-assisted removal is preferable and practicable for young girls, compared with the open procedure. The patient adhered well to the surgical intervention.
