微小肝癌的声像图特征与病理组织学的对比分析

本文报告超声诊断3例4个微小肝癌。超声显示病灶形态多为圆形或卵圆形,边界清楚,内部显示无回声暗区,边缘高回声圈等。文中对微小肝癌声像图特征的病理基础进行了探讨。通过对比分析,得出如下结论:(1)显示暗区回声的微小肝癌结节在组织学上是高分化、无出血坏死或间质纤维化,缺乏汇管区的实质性肿瘤;(2)边缘出现高回声圈的微小肝癌结节在组织学上是厚包膜的肿瘤

Ultrasonographic Features of Microhepatic Carcinoma and Histopathology Study

Three patients with total four minute hepatic carcinomas (MHC) were detected by ultrasonography and checked by operation and/or biopsy. They were all appeared as oval or round mass with definite margin. The internal echoes appeared dark with high echoic halo around,The histopathology foundation of the ultrasonographic features of MHC was discussed. The author concluded that: 1. The internal echoic dark region of the MHC represented high differentiated cells of the tumor without necrotic and fibrotic tissues ,or lack of collected ducts. 2. Peripheral hyperechoic halo represented the thick and solid capsule of the MHC.
