目的 探讨形成肝癌超声不同回声的组织病理学基础。方法 经超声引导对肝脏 186个实性不同回声病灶行穿刺组织学活检 ,分析与灰阶声像图相对应的组织病理改变。结果 90例肝癌中低回声者组织结构致密 ,细胞成分简单 ,声像图上有低回声暗环者有包膜。当癌组织内有大片脂肪变性、透明细胞或非液化性不均匀性坏死时 ,声像图上显示为高回声。除肝癌外的肝内实性占位病变具有上述组织病理改变时 ,可形成与肝癌相似的声像图回声。结论 肝癌声像图上的不同回声是其组织病理改变的声学表现。组织病理成分和构成决定了肝癌的回声特性
Objective To explore the histopathological basis of different echoes of liver cancer. Methods Ultrasound-guided puncture histological biopsies were performed on 186 solid echo lesions in the liver, and histopathological changes corresponding to gray-scale sonograms were analyzed. RESULTS: The hypoechoic tissues of 90 patients with hepatocellular carcinoma were dense in structure, simple in cell composition, and enveloped by hypoechoic rings on the sonogram. When there is a large area of steatosis, clear cells, or non-liquefied inhomogeneous necrosis in the cancerous tissue, high echoes appear on the sonogram. In addition to hepatocellular carcinoma, solid hematopoietic lesions with the above histopathological changes can form echograms similar to liver cancer. Conclusion The different echoes on the sonogram of liver cancer are the acoustic manifestations of histopathological changes. Histopathological components and composition determine the echogenic properties of liver cancer
