Chinese Journal of Ultrasound in Medicine(2013)
Abstract
患者女,46岁,已婚.1月余前发现左下腹肿块,约鹌鹑蛋大小.患者3年前因“左侧卵巢交界性肿瘤”在外院行“腹腔镜下卵巢肿瘤切除术”.体检:腹平软,无压痛及反跳痛,左下腹壁肿块,质中,边界清晰,活动欠佳,表面皮肤无发红及破溃,左侧腹股沟淋巴结未及肿大.CA-125:22.1 U/ml.超声检查:左下腹腹直肌内有3.7 cm×3.0 cm不均质中等回声肿块,边界清晰,形态尚规则,内可见点状强回声(图1),彩色多普勒血流现象示肿块内可见较丰富血流信号(图2),频谱多普勒测及动静脉频谱,阻力指数0.87.弹性成像显示该肿块弹性应变率比值为5.79(图3).超声提示:左下腹腹直肌内实质性肿块.患者行左下腹壁肿块局部广泛切除术,术中见肿块位于腹直肌肌层内,大小约4.0 cm×3.0 cm,边界清晰,质硬,外侧达前鞘外侧缘,前方至前鞘之腹内斜肌腱膜.术后病理诊断:左腹壁转移性浆液性乳头状囊腺癌(免疫组化考虑卵巢来源).
