肝脏钙化性病变超声诊断结果及其与年龄分布关系

RELATIONSHIP BETWEEN CALCIFIED LESION IN LIVER DIAGNOSED BY ULTRASONOGRAPHY AND AGE DISTRIBUTION

目的探讨肝脏钙化性病变的超声诊断结果及其与年龄分布的关系。方法对23 800例健康体检者中经腹部彩色多普勒超声检查发现肝脏钙化性病变病人的临床资料进行回顾性分析。结果肝脏钙化性病变425例,总检出率为1.9%;其中单发350例,多发102例;钙化性病变的大小为3~40 mm;分布在右肝335例,左肝96例,全肝21例。肝脏实质非特异性钙化灶310例（68.58%）,年龄多分布在20~60岁,占73.95%,与≥70岁年龄组比较差异有显著性（t=3.65,P〈0.05）;肝内管壁钙化81例,年龄多分布在60岁以上,与其他年龄组比较差异有显著性（t=3.15,P〈0.05）;肝囊肿壁钙化32例,肝血管瘤钙化19例,肝癌钙化4例,肝部分切除术后4例,肝外伤后2例,年龄多发生在40岁以后。结论肝脏钙化性病变可发生在任何年龄,不同类型的钙化性病变的年龄分布有一定的差异;肝实质非特异性钙化居多,是肝脏先天性或某些病变稳定或愈合后的一种病理性改变。超声检查是最简便、最可靠的诊断方法之一。

Objective To explore the results of calcified lesion in liver detected by ultrasonography and its correlation with age distribution.Methods A retrospective review was done in clinical data of 23 800 patients with hepatic calcified lesion found at abdominal color Doppler ultrasonography.Results Calcified lesion in liver was found in 425 cases,with a total detection rate of 1.9%,in which,solitary lesion was noted in 350 cases,and multiple in 102.The lesions located were： 335 cases in right liver,96 in left liver and 21 in whole liver,with a diameter ranged from 3 mm to 40 mm.Nonspecific hepatic calcification was found in parenchyma in 310 cases（68.58%）,mostly（73.95%） in 20-60-year groups,the difference was significant as compared with ≥70-year group（t=3.65,P〈0.05）;Calcification of tuber wall in liver was noted in 81 cases of those over 60 years of age,the differences being significant compared with other age groups;Calcification in wall of hepatic cyst was found in 32 cases,in hemangioma 19,in hepatoma four,in after partial hepatectomy four,and in post-traumatic liver two,most of them over 40 of age.Conclusion The calcified disease in liver may develop in any age,the age distribution in various lesions was different.Most of the lesions are non-specific calcification in liver parenchyma,which is congenital or a type of pathologic changes after some diseases in liver.Ultrasonography is one of the simplest and most reliable diagnostic methods of this condition.
