A case of rare mullerian anomaly-functional rudimentary uterine horn: As an unusual cause of unilateral dysmenorrhea in postmenarchal adolescent girl

Abstract

An 18-year-old girl presented with progressively increasing dysmenorrhea. A pelvic mass was suspected which on exploratory laparotomy was found to be a rudimentary horn (hematometra, hematosalpinx). We report a case of unicornuate uterus with functioning rudimentary horn to highlight that mullerian duct anomalies should be considered in the differential diagnosis of severe dysmenorrhea even in normally menstruating girls. Unicornuate uterus with a rudimentary horn is susceptible to many gynecologic and obstetric complications. Hematometra, chronic pelvic pain, endometriosis, infertility are some of the complaints in women with unicornuate uterus.
