Delayed diagnosis of a non-communicating right uterine horn: A case report and literature review

BackgroundAccurate diagnosis of a müllerian anomaly is essential for appropriate management and prevention of complications. However, diagnosis is often missed or delayed. CaseThis is a case of a nulliparous woman with a müllerian anomaly diagnosed at the age of 36 despite prior evaluation with ultrasound and laparoscopy. Magnetic resonance imaging (MRI) suggested a unicornuate uterus with a right non-communicating rudimentary horn. Hysteroscopy and chromopertubation confirmed the diagnosis. The rudimentary horn was resected laparoscopically using bipolar energy. ConclusionAn undiagnosed müllerian anomaly should be considered in the setting of persistent dysmenorrhea. Three-dimensional ultrasound or MRI should be used judiciously in patients with refractory dysmenorrhea or when ultrasound raises concern for a müllerian anomaly.
