目的:提高彩超对弥漫性肝癌的诊断率。方法:对经CT及临床病理证实的63例弥漫性肝癌的超声图像特征及临床特点进行了总结分析。结果:本文患者二维超声显示:全部患者均有肝包膜改变,77.8%(49/63)呈波浪状改变,22.2%(14/63)呈锯齿样改变,90.5%(57/63)肝脏肿大,28.6%(18/63)合并门静脉栓塞。弥漫性肝癌声像图大体分二种类型:弥漫小结节型和“豹皮样”斑块型,其中87.3%(55/63)为弥漫小结节型,12.7%(8/63)为“豹皮样”斑块型。本文患者CDFI显示:肝内血流信号走行失常,分布紊乱,可见血管绕行或散在斑点状、短棒状血流信号。结论:肝包膜凹凸不平、肝实质回声呈弥漫小结节或“豹皮样”斑块改变、肝内血流信号失常、门静脉栓塞等彩超图像特征对诊断弥漫性肝癌具有重要的价值,但彩超诊断弥漫性肝癌仍存在一定的难度,重点需要与肝硬化、乙型肝炎等进行相鉴别。
Objective: To improve the diagnosis of diffuse color Doppler echocardiography. Methods: The characteristics and clinical features of 63 cases of diffuse hepatocellular carcinoma confirmed by CT and clinicopathological findings were analyzed. Results: Two-dimensional ultrasonography showed that all the patients had hepatic capsule changes, with wavy changes in 77.8% (49/63), serrated changes in 22.2% (14/63), liver in 90.5% (57/63) Swollen, 28.6% (18/63) with portal vein embolism. Diffuse hepatocellular carcinoma sonographic images generally divided into two types: diffuse nodules and “leopard skin ” plaque type, of which 87.3% (55/63) were diffuse nodules, 12.7% (8/63 ) For “leopard skin ” plaque type. In this paper, patients with CDFI showed: intrahepatic flow of blood signal disorder, the distribution of disorders, showing bypass or scattered blood vessels in the shape of a short rod-like blood flow signal. Conclusions: The hepatic capsule is irregular and the echoes of the hepatic parenchyma are diffuse small nodules or “leopard skin” plaque changes. Hepatic blood flow abnormalities, portal vein embolization and other ultrasonographic features are of great value in the diagnosis of diffuse liver cancer , But color Doppler ultrasound diagnosis of diffuse liver cancer still exists a certain degree of difficulty, the key need and liver cirrhosis, hepatitis B phase identification.
