This case report describes a 23-year-old nulligravida woman with dysmenorrhea and vaginal spotting who was evaluated with hysterosalpingography and MRI to identify a right unicornuate uterus, a left non-communicating rudimentary horn, and an ipsilateral ovarian endometrioma; CT also showed absence of the left kidney and ureter. After CT angiography was used to assess uterine artery course, the authors performed laparoscopy, where the rudimentary horn was initially difficult to identify due to a large endometrioma and dense adhesions; following adhesiolysis, the rudimentary horn was removed laparoscopically along with ipsilateral salpingo-oophorectomy without complications. The report is limited by its single-case design and does not provide comparative outcomes. The paper presents a reproductive tract Müllerian anomaly associated with endometriosis and specifically documents an ipsilateral ovarian endometrioma in the surgical management context, making it directly relevant to endometriosis.

Abstract

A unicornuate uterus with a non-communicating rudimentary horn is a rare Müllerian anomaly that has been associated with various comorbidities including hematometra, endometriosis and obstetric complications. Laparoscopy has proven to be an effective and minimally invasive surgical approach to the management of uterine anomalies. We present the case of a 23-year-old nulligravida woman with dysmenorrhea and vaginal spotting. Hysterosalpingogram and magnetic resonance imaging revealed a right unicornuate uterus, left rudimentary horn and ipsilateral ovarian endometrioma. In addition, computed tomography (CT) demonstrated absence of the left kidney and ureter. The course of the patient's uterine artery was examined with CT angiography. At laparoscopy the rudimentary horn was not identified initially because of the large endometrioma and dense adhesion. After adehesiolysis, laparoscopic removal of the rudimentary horn and ipsilateral salpingo-oophorectomy was performed without complications. The CT angiography was useful for the safe performance of laparoscopic management of this case.
