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。
This article retrospectively analyzed 120 cases of intrahepatic space-occupying lesions after 1987-11-1994-11 breast cancer surgery, of which 98 cases were metastatic cancers and 22 cases were heterogeneous fatty liver, hepatic cysts, or hemangiomas. It was confirmed by needle biopsy, diagnostic chemotherapy, comprehensive imaging diagnosis and ultrasound follow-up. The incidence of fatty liver was higher in breast cancer patients (47%), and in 35 cases (36%) of liver metastases and fatty liver, the sonogram features internal hypoechoic (66%) and no hypoechoic halo around the breast. 69%); without fatty liver in 63 cases (64%), the internal echoes were mostly (59%), often with low echo halo (76%). The presence of fatty liver attenuates the echo of the liver, which may lead to unclear occupancy and missed diagnosis. The presence of fatty liver often leads to misdiagnosis of some occupying lesions. When the sonogram is not typical and the differential diagnosis is difficult, ultrasound-guided biopsy should be used to make a qualitative diagnosis.
