摘　　要：目的探讨肝孤立性坏死结节的超声表现及临床诊断价值。方法回顾性分析2018年10月至2020年6月于医院经病理诊断为肝孤立性坏死结节的48例患者的临床资料,所有患者均接受二维超声、彩色多普勒超声与超声造影检查,分析肝孤立性坏死结节的超声表现及临床诊断价值。结果经手术治疗或肝穿活检证实,48例患者共50个病灶均为肝孤立性坏死结节。二维超声检查结果显示,48例患者共50个病灶,其中左叶10个,右叶40个;病灶低回声42个,中等回声4个,中低混合4个;病灶边界清晰40个,边界模糊10个;35个病灶形态规整(为椭圆形或圆形),15个病灶形态不规整(为结节融合样、串珠样)。彩色多普勒超声检查结果显示,病灶无血流信号。超声造影检查结果显示,20个病灶动脉相、门脉相及延迟相均无造影剂填充且无增强,30个病灶动脉相病灶周边为薄环状高增强。结论肝孤立性坏死结节的超声造影表现为病灶内三相呈无增强或病灶周边呈薄环状增强,具有较高的临床诊断价值。Objective The ultrasonographic features of hepatic solitary necrotic nodule and their clinical diagnostic value were investigated.Methods The clinical data of 48 patients with hepatic solitary necrotic nodule diagnosed by pathology in the hospital from October 2018 to June 2020 were retrospectively analyzed.They underwent two-dimensional ultrasonography,color Doppler ultrasonography and contrast-enhanced ultrasonography respectively.The ultrasonographic features of hepatic solitary necrotic nodule and their clinical diagnostic value were analyzed.Results 50 lesions in 48 patients were confirmed by surgical treatment or liver biopsy.Of two-dimensional ultrasonography:a total of 50 lesions were detected in 48 patients,10 in the left lobe and 40 in the right lobe;There were 42 hypoechoic lesions,4 moderate echoic lesions and 4 moderate and hypoechoic mixed lesions;40 lesions had clear boundary and 10 lesions had fuzzy boundary;35 lesions were regular(oval or round)and 15 lesions were irregular(nodular fusion and beaded).Color Doppler ultrasonography showed no blood flow signals.Contrast-enhanced ultrasonography showed that there was no contrast medium filling and enhancement in arterial phase,portal phase and delayed phase in 20 lesions,and thin ring high enhancement was found around arterial phase in 30 lesions.Conclusion Contrast-enhanced ultrasonography of hepatic solitary necrotic nodule shows no enhancement in the three phases of the lesion or thin ring enhancement around the lesion,which has high clinical diagnostic value.
