Inappropriate surgery in a patient with misdiagnosed Robert’s uterus

Background: Robert’s uterus is a rare Mullerian anomaly, which can be described as an asymmetric, septate uterus with a non-communicating hemicavity. Herein, we present the case of a misdiagnosed Robert’s uterus, resulting in an invasive and disadvantageous surgery. Case presentation: A 16-year-old woman was referred to our department because of dysmenorrhea and suspicion of uterine malformation. We misdiagnosed Robert’s uterus as a unicornuate uterus with a non-communicating rudimentary horn and hematometra, and performed laparoscopic hemi-hysterectomy. Although the patient’s symptoms were relieved, our surgical procedure left the lateral uterine wall weak, making the patient’s uterus susceptible to uterine rupture in any future pregnancy. Conclusions: Although the early diagnosis of Robert’s uterus is challenging, it is important in order to determine appropriate surgical interventions and management for maintaining the quality of life and ensuring safety in future pregnancies.
