摘要
目的分析超声结合CT影像学特征在囊型肝包虫病中的临床应用价值。方法回顾性分析本院2017年2月至2019年10月收治的66例囊型肝包虫病患者的临床资料,比较超声和CT检查对囊型肝脏包虫病各型的诊断准确率;分析囊型肝脏包虫病各型的影像学特征。结果超声联合CT诊断囊型肝脏包虫病各型的总诊断准确率为96.97%,明显高于单一的CT(81.82%)和超声检查(78.79%)(P<0.05);CE1型主要表现为圆形或类圆形的囊性团块,均为单房;CE2型主要表现为囊状结构,均为多房,呈“玫瑰花结征”或者“蜂窝征”改变;CE3a型主要表现为“飘带征”,还可见“水中百合花征”;CE3b型超声可见“囊中囊”特征性影像;CE4型可见密度强弱相间的“脑回证”;CE5型可见囊壁明显钙化。结论超声检查及CT检查均可有效显示囊型肝包虫不同病理阶段的影像学特征表现,术前结合超声和CT检查可有效提高诊断准确率。
Objective To analyze the clinical application value of ultrasound combined with CT imaging features in cystic hepatic echinococcosis.Methods The clinical data of 66 patients with cystic hepatic echinococcosis admitted to our hospital from February 2017 to October 2019 were retrospectively analyzed.The diagnostic accuracy of ultrasound and CT examination for various types of cystic hepatic echinococcosis was analyzed.The imaging features of various types of cystic hepatic echinococcosis were analyzed.Results The total diagnostic accuracy of ultrasound combined with CT in the diagnosis of cystic hepatic echinococcosis was 96.97%,which was significantly higher than that of single CT(81.82%)and ultrasonography(78.79%)(P<0.05).CE1 type mainly showed round or round-shaped cystic masses,all of which were unilocular.CE2 type mainly showed cystic structure,all of which were plurilocular,showing a change of"rosette sign"or"honeycomb sign".The CE3 a type mainly showed"streamer-like sign"or"lily sign in water".The CE3 b type of ultrasound can be seen with the"sac in sac"characteristic image.The CE4 type can be seen with the"gyrus sign",with alternate strong and weak densities.The CE5 type showed obvious calcification of the cyst wall.Conclusion Ultrasonography and CT examination can effectively show the imaging features of different pathological stages of cystic hepatic echinococcosis.Preoperative ultrasound combined with CT examination can effectively improve the diagnostic accuracy.
