Abdominal Wall Endometriosis Diagnosed by Ultrasonography: A Case Report

报告一例经超声诊断的腹壁子宫内膜异位症患者。该患者有剖宫产手术史；手术切口瘢痕处结节，质硬，边界欠清，有触痛；有与月经相关的周期性切口瘢痕处疼痛等临床表现；超声表现：肿块位于腹壁切口处皮下软组织内，呈中低回声结节，边界欠清，形态欠规则，且彩色多普勒血流显像显示肿块内部及边缘可见血流信号，脉冲多普勒显示血流信号为低速高阻的动脉频谱。考虑符合腹壁子宫内膜异位症的诊断。术后病理诊断为子宫内膜异位症伴炎症反应。超声检查具有简便、快捷、经济、无痛苦、可重复性强等优点，并能动态观察病情变化，是诊断子宫内膜异位症的首选方法。 A patient with abdominal wall endometriosis diagnosed by ultrasonography was reported. The patient had a history of cesarean section. A hard and tender nodule with unclear border was found at the scar of surgical incision. There was periodic scar pain related with menstruation. Ultraso-nography showed the nodule located in the subcutaneous soft tissue of the surgical incision, with low echoes, unclear border and irregular shape. Color Doppler showed blood flow signals around and inside the mass, which were demonstrated as “low speed and high resistance” by Pulse Doppler. The data above supported the diagnosis of endometriosis. The pathologic diagnosis after surgery was endometriosis accompanied with inflammatory reaction. Ultrasonography had many advantages such as convenient, fast, inexpensive, painless, and repeatable. In addition, it could monitor the changes of diseases. Ultrasonography was the preferred method for diagnosis of endometriosis.
