【摘要】 本文回顾性分析了１９８７－１１～１９９４－１１乳腺癌术后肝内占位性病变１２０例，其中９８例为转移癌，２２例为非均匀性脂肪肝、肝囊肿或血管瘤。采用针吸活检、诊断性化疗、综合影像学诊断及超声随访方法证实。乳腺癌术后出现脂肪肝的比例较高（４７％），肝转移伴脂肪肝者３５例（３６％），其声像图特点为内部呈低回声（６６％）及周围无低回声晕（６９％）；而不伴脂肪肝者６３例（６４％），其内部多呈等回声（５９％），常伴低回声晕（７６％）。脂肪肝的存在使肝脏回声衰减，可能导致占位显示不清而漏诊；脂肪肝的存在又往往使得一些占位病变表现不典型而误诊。当声像图不典型、鉴别诊断困难时，应做超声引导下穿刺活检予定性诊断。更多还原

【Abstract】 We reviewed the ultrasound diagnosis data of 120 Patients between November 1987 and November 1994. Of them, 98 cases were confirmed as the metastasis and 22 as heterogenous fatty liver, hepatic cyst and cavernous hemangioma by biopsy, diagnostic chemotherapy or by diagnostic imaging (US, CT, MR and angiography) and ultrasonic follow-up. There was a high rate (47%)of fatty liver after breast cancer operation.The metastatic lesions were ultrasonographically classified as two groups: those with (n=35) and those without fatty liver (n=63), the former showed a more special hypoechoic nodule (66%)without“halo” sign (69%); The later showed a homoechoic inside (59%)and with "halo" (76%).Being within the fatty liver, the lesions were easy to be leaked because of declined parenchymal echo, especially at the posterior part of the liver. and misdiagnosed for untypical shown If the image isn’t typical and the differential diagnosis is difficult, biopsy should be done by sonographically guided fine-needle.更多还原
