肝脏CT表现为囊性病变时,可能为许多种疾病的病理反应。按病因可分为:(1)先天性:如肝囊肿;(2)创伤性;(3)炎症性:如肝脓肿;(4)寄生虫性:如肝包虫囊肿;(5)肿瘤性:如肝囊性转移瘤;(6)其他:如肝梗死等。现将肝囊性病变的CT表现分为7组加以讨论如下。1囊肿呈均一的水样密度性病变:先天性肝囊肿属于此类病变。CT表现为单发或多发圆形、椭圆形均质水样密度影,边缘光滑锐利,CT值约为0～15Hu之间。由于部分容枳效应的影响,小囊肿的CT值常偏高,应薄层扫描以确诊。增强扫
Liver CT manifestations of cystic lesions, the pathological response may be many diseases. According to the cause can be divided into: (1) congenital: such as liver cysts; (2) traumatic; (3) inflammatory: such as liver abscess; (4) parasitic: hepatic hydatid cysts; : Such as liver cystic metastases; (6) other: such as liver infarction. Liver cystic lesions now CT performance is divided into 7 groups to be discussed as follows. 1 cysts were uniform watery density lesions: congenital liver cysts are such lesions. CT showed single or multiple round, oval homogeneous water density, sharp and sharp edges, CT value of about 0 ~ 15Hu between. As part of the effect of Rong Hovenia, CT small cysts often high, should be confirmed by thin-layer scan. Enhanced scan
