摘要
目的 :探讨小肝癌 (≤ 3cm)超声回声水平与病理组织学类型及分化之间的关系。材料和方法 :对 73例肝细胞肝癌患者的 85个结节 (≤ 3cm)的超声回声水平、病理组织学类型及分化程度进行观察分析。结果 :本组小肝癌以高分化为主 ,其中 ,小梁型、紧密型及硬化型的超声图像以低回声表现为主 ,腺泡型则高、中、低回声散在分布。结论 :小肝癌以低回声表现为主 ,其回声水平仅反应内部结构的均一性 ,与病灶的病理组织学类型及分化程度并无严格的对应关系。
Purpose: The echo pattern of small hepatocellular carcinoma (HCC) in liver ultrasound was studied in light of their pathologic characteristics. Materials and Methods: Echo patterns, histological types and differentiation degrees of 85 HCC lesions of 3cm or less in diameter, most of them well differentiated, were retrospectively analyzed. Results: Small HCC of trabecular, compact and cirrhotic type were seen as hypoechoic nodules. While glandular type was characterized as mixture of hyper-、iso- and hypoechogenic. When intracellular fatty degeneration present, the trabecular HCC became to hyper- or mixed echoic. Conclusion: Most of the small HCC were hypoechogenic, but the echo pattern doesn’t parallel with the histopathologic type or differentiation degrees of the lesion.
