Unusual laparoscopy finding with previous laparotomy for endometrioma: a rare case report

Area of Science:

• Reproductive Medicine
• Surgical Gynecology
• Congenital Anomalies

Background:

• Severe dysmenorrhea in young women can significantly impact quality of life.
• Endometriomas were suspected as the cause of pain, leading to hormonal treatment with danazol and gonadotropin-releasing hormone agonist depot injections.
• Previous laparotomy for endometriomas did not resolve the severe pain.

Observation:

• Laparoscopy revealed a large, noncommunicating, functioning rudimentary uterine horn.
• The patient also had ipsilateral renal agenesis, a common association with uterine anomalies.
• The rudimentary horn was suspected to be the source of the dysmenorrhea.

Findings:

• Laparoscopic excision of the rudimentary horn resulted in major relief from severe dysmenorrhea.
• The previously suspected endometriomas were not the primary cause of the patient's debilitating pain.
• This case underscores the diagnostic challenge posed by Müllerian duct anomalies.

Implications:

• Accurate diagnosis of congenital uterine anomalies is crucial for effective management of severe dysmenorrhea.
• Surgical intervention for rudimentary horns can resolve pain when endometriosis is incorrectly implicated.
• Awareness of the association between renal agenesis and uterine anomalies aids in comprehensive patient evaluation.
