Objective: To report 2 very rare cases of young women who presented with severe dysmenorrhea and a large cystic lesion in the myometrium, which presented a diagnostic dilemma because they were confused with a Müllerian anomaly. Design: Case reports and a literature review. Setting: A university-based reproductive endocrinology and infertility clinic in the United States. Patient(s): An 18- and a 16-year-old nulliparous girl presented with worsening of their longstanding pelvic pain, and imaging study results were suggestive of a Müllerian anomaly. Intervention(s): Abdominal and pelvic computed tomography, transvaginal ultrasonography, pelvic magnetic resonance imaging, operative laparoscopy, and excision of a juvenile cystic adenomyoma (JCA). Main Outcome Measure(s): Resolution of the pelvic pain and restoration of normal uterine anatomy after appropriate intervention Result(s): Restoration of normal uterine anatomy, which was confirmed by 3-dimensional ultrasonography for case 1; however, case 2 still had a small remnant of JCA postoperatively. Conclusion(s): Clinical and radiologic examinations may not be useful in differentiating a Müllerian anomaly from other rare abnormalities like JCA. When in doubt, laparoscopy can assist in diagnosing and treating the condition.
