Laparoscopic Diagnosis and Treatment of an Isolated Cervical Diverticulum

Background: Congenital müllerian anomalies are found in 8.0% of women with infertility and up to 5.5% of women in a general population. Cervical diverticulum is a type of cervical malformation that can be congenital or acquired, with only select cases documented in the literature. Cervical diverticulum can be asymptomatic or present with abnormal uterine bleeding, pelvic pain, or infertility. Previously described management options are largely limited to observation or exploratory laparotomy. Case: A 35-year-old woman, gravida 2 para 2, presented with persistent menorrhagia, pelvic pain, and abdominal bloating and was found to have an 8-cm right adnexal mass on pelvic ultrasonography. Magnetic resonance imaging showed a hemorrhagic cervical mass communicating with the uterine cavity. The mass was resected laparoscopically, and pathology revealed fibromuscular tissue with endocervical epithelium consistent with a cervical diverticulum. Conclusion: Isolated cervical diverticula are rare but should be considered in the differential diagnosis of adnexal masses. Laparoscopic surgery is a safe, minimally invasive approach for evaluation and repair of cervical diverticula.
