本文报告５０３例转移性肝癌的临床表现和超声特征。转移性肝癌的原发肿瘤涉及２６个部位２８种组织学类型，以原发于肺者最多见，占２２．０７％。从原发肿瘤确诊至发现肝转移的时间从１月至３年不等，１年以内占８３．３０％。１１８例（２３．４７％）肝转移癌有临床症状和体征，其中肝肿大５０例（９．９４％）。多发肝转移灶占７２．７６％，声象图表现以高回声型居多，低回声型其次，二者共７６．５４％；病灶周边有透声晕者４２．５４％。３２例经彩色多普勒超声检查，４３．７５％肿瘤内检测出动脉频谱，其中ＲＩ＞０．５占９２．８６％（１３／１４）。本文并对超声检查肝转移癌的临床意义进行了分析。
This article reports the clinical manifestations and ultrasound features of 503 cases of metastatic liver cancer. The primary tumor of metastatic liver cancer involves 28 sites of 26 histological types at 26 sites, the most common of which is primary lung cancer, accounting for 22.07%. The time from the diagnosis of the primary tumor to the detection of liver metastasis ranged from January to 3 years, accounting for 83.30% within 1 year. 118 cases (23.47%) of liver metastases had clinical symptoms and signs, of which hepatomegaly was 50 cases (9.94%). Multiple hepatic metastatic lesions accounted for 72.76%. Acoustic images showed mostly hyperechoic type, hypoechoic type followed, with a total of 76.54%; 42.54% of the lesions were surrounded by sound-sounding. In 32 patients undergoing color Doppler ultrasonography, the arterial spectrum was detected in 43.75% of the tumors, with RI > 0.5 accounting for 92.86% (13/14). In this paper, the clinical significance of ultrasound examination of liver metastases was analyzed.
