AbstractPrimary utero-cervical diverticulum is a rare Müllerian anomaly and clinical manifestation of this condition had not beenwell documented. Here, we report a woman who presented with huge mass occupied abdominal cavity, which wesuspected as fibroids developed at the one side of uterus bicornis unicollis. Within surgical and histological exploration,the tumor turned out to be developed from utero-cervical diverticulum.

Case

Uterine diverticulum is a rare anomaly of the uterus, however, several cases have been reported which are thought to beformed due to unilateral distal non-fusion of Müllerian duct [1] . Furthermore, myoma developed at uterine diverticulum ismuch rarer. Appropriate surgical intervention is mandatory for accurate diagnosis and symptom relief.
