腹部超声在诊断老年非均匀性脂肪肝中的应用价值

The value of ultrasound in diagnosis of non-uniform fatty liver in the elderly

目的探讨腹部超声辅以彩色多普勒检查在诊断老年非均匀性脂肪肝中的应用价值。方法收集23例最终被其他方法确诊为非均匀性脂肪肝的老年患者的肝脏超声图像,回顾性分析这些患者腹部超声以及彩色多普勒的数字和图象资料,找出其内在规律并评价其在诊断老年非均匀性脂肪肝中的应用价值。结果所有23例老年患者腹部超声图象中没有一例患者的腹部超声图象表现为占位效应,其中Ⅰ型局限浸润型2例,Ⅱ型多灶浸润型1例,Ⅲ型叶段浸润型1例,Ⅳ型弥漫非均匀浸润,残存小片正常区19例;彩色多普勒检查示有7例肝内异常强回声或弱回声区(直径均>3.0cm),内部或周边可见正常血管分支走行。结论非占位效应也是老年非均匀性脂肪肝的最重要特征,在诊断老年非均匀性脂肪肝中具有同样高的应用价值。

Objective To explore the value of ultrasound in diagnosis of non-uniform fatty liver in the elderly. Methods The ultrasonograms of twenty-three old patients with non-uniform fatty liver were collected and the pictures and digital data were analyzed retrospectively to find out their features and the value of ultrasound in diagnosis of non-uniform fatty liver in the elderly. Results The abdominal ultrasonograms of all 23 eases showed ＂no space- occupying effect＂. Among them, pattern Ⅰ , localized infiltration, was seen in 2 cases（8.7%）; pattern Ⅱ , multiple nodular infiltration, in 1 ease （4.3 % ） ; pattern Ⅲ , lobe/segmental infiltration, in 1 ease（4.3% ） ; pattern Ⅳ, diffuse non-uniform infiltration in 19 eases （82.6%）. Color Doppler Flow Image showed hyperechoic or hypoechoic areas in the liver with normal vessels in or at the peripheral area of the liver in 7 eases. Conclusions The most important character of non-uniform fatty liver was ＂no space occupying effect＂ in the elderly. Ultrasound plays a very important role in diagnosis of non-uniform fatty liver in the elderly.
