摘　　要：目的:探讨不同病理类型原发性小肝癌的超声造影表现,为临床治疗提供依据。方法:回顾分析62例经病理证实的原发性小肝癌的超声造影资料。结果:62例71个病灶,其中高分化33个、中分化30个和低分化8个;梁索型44个、假腺管型13个、实体型9个和纤维硬化型5个。高、中、低分化程度原发性小肝癌造影开始增强时间分别为(14.08±3.94)、(13.51±3.35)、(12.86±2.89)s,达峰时间分别为(29.41±7.10)、(28.14±6.94)、(26.56±6.56)s,消退时间分别为(99.83±12.38)、(72.32±10.25)、(42.19±10.03)s,开始增强时间和达峰时间的差异均无统计学意义(P>0.05),但消退时间的差异有统计学意义(P<0.05)。不同病理类型原发性小肝癌患者造影剂动脉相增强模式差异无统计学意义(P>0.05),门脉相、延迟相增强模式差异有统计学意义(P<0.05)。结论:不同分化程度、不同病理类型原发性小肝癌超声造影表现特征存在差异,超声造影对其临床治疗有重要的参考价值。Objective：To investigate the ultrasonograms of different pathologic types of primary small hepotocellular carcinoma, and to provide foundations for clinical treatment.Method：The ultrasonographic data of 62 patients with pathologically confirmed primary small hepotocellular carcinoma were retrospectively analyzed.Result：The 62 patients had 71 lesions, among which, 33 lesions were well differentiated, 30 le-sions moderately differentiated, and 8 lesions poorly differentiated; 44 lesions were trabecular, 13 lesions pseudoglandular, 9 lesions solid, and 5 lesions scirrhous.The initial enhancement times of well, moderately, and poorly differentiated primary small hepotocellular carcinoma were （ 14.08 ±3.94） seconds, （ 13.51 ±3. 35） seconds, and （12.86±2.89） seconds, respectively;the peak times were （29.41±7.10） seconds, （28. 14±6.94） seconds, and （26.56±6.56） seconds, respectively; and the regression times were （99.83±12. 38） seconds, （72.32±10.25） seconds, and （42.19±10.03） seconds, respectively.The differences in initial enhancement time and peak time were statistically insignificant （ P〉0.05） , but the differences in regression time were statistically significant （ P〈0.05） .The differences in the enhancement pattern of contrast media in arterial phase between different pathologically typed primary small hepotocellular carcinoma were statistically insignificant （ P〉0.05） , but those in the enhancement patterns of contrast media in portal and lag phases were statistically significant （P〈0.05）.Conclusion：There are differences in ultrasonographic manifestation feature between different differentiated and different pathologically type primary small hepotocellular carcino-ma, and ultrasonography has important reference values for the clinical treatment.
