Chinese Journal of Interventional Imaging and Therapy(2021)
Abstract
目的 观察剖宫产术后腹壁子宫内膜异位症(AWE)MRI表现.方法 回顾性分析12例经术后病理证实的剖宫产术后AWE患者.结果 12例均为单侧病变,位于剖宫产手术横切口附近;11例形态不规则、边界模糊,1例呈类圆形、边界清晰;11例呈囊实性,1例为囊性病变;囊实性病变T1WI呈不均匀等/低信号、脂肪抑制T2WI为高低不等混杂信号,囊性病变呈较均匀T1WI稍高信号、脂肪抑制T2WI等/稍高信号;增强MRI囊性病变及囊实性病变的囊性成分均未见强化,实性成分见较明显强化,病变范围较平扫增大,边缘不规则,与正常组织界限不清.结论 剖宫产术后AWE的M RI表现具有一定特征性,有助于诊断.
