  A noncommunicating rudimentary uterine horn with functioning endometrium is a congenital Müllerian anomaly known to cause menorrhagia and abdominal pain. Here, we present two patients with a type 2b uterine anomaly (American Society for Reproductive Medicine classification) and successful laparoscopic resection of the rudimentary horn in each.

  Case 1. A 21-year-old female with a history of repeated clinic visits for menorrhagia was referred to our hospital due to findings showing an ovarian cystic tumor. CT and MRI results revealed an endometriotic cyst of the left ovary, left noncommunicating rudimentary uterine horn with functioning endometrium, and co-lateral renal agenesis. Laparoscopic resection of the rudimentary horn and left uterine adnexa was performed, after which the symptoms improved.

  Case 2. A 41-year-old female underwent a laparoscopic cystectomy of the right ovary at 28 years of age and her uterus was suspected to be bicornuate at that time. However, that operation was apparently ineffective for alleviation of menorrhagia, and the patient was referred to our hospital due to its persistence as well as suspicion of endometriosis. MRI revealed a right noncommunicating rudimentary uterine horn with functioning endometrium. Laparoscopic resection of the rudimentary horn and right uterine adnexa improved the symptoms.
