A 31-year-old woman presented with a mass in her groin accompanied by intense pain during the menstrual period. A poorly circumscribed, elastic, hard mass was palpable in her right inguinal region. Magnetic resonance imaging showed that the mass had continuity with the inguinal course of the round ligament of the uterus. The mass lesion was well enhanced with high intensity on diffusion-weighted imaging. An operation was performed, and the histological diagnosis was endometriosis of the round ligament. After operation, she was completely relieved of pain. It is important to include endometriosis in the differential diagnosis in women with painful inguinal mass lesions at risk for endometriosis.
一名31岁女性腹股沟出现肿物，经期伴有剧痛。在其右侧腹股沟区可触及一个边界不清、有弹性的硬块。磁共振成像显示该肿物与子宫圆韧带的腹股沟走行相连。肿物在扩散加权成像上呈高强度强化。进行了手术，组织学诊断为子宫圆韧带子宫内膜异位症。术后，她的疼痛完全缓解。对于有子宫内膜异位症风险且腹股沟有疼痛性肿物病变的女性，在鉴别诊断中纳入子宫内膜异位症很重要。
