| 中文摘要: |
| 本文对25例先天性胆管囊状扩张症根据CT表现分为三种类型：①肝内型；②肝外型；③混合型。肝内型具有特征性CT表现为扩张呈囊状的胆管将门静脉分支包绕,在增强CT或胆道造影CT均可显示出“中心圆点。征象。肝外型囊壁见突出腔内结节时为癌变征象。CT对本病的显示准确率达100%.对照其它影像检查方法,作者认为：超声对本病也有重要诊断价值；X线胆道造影诊断价值不大；ERCP和PTC为痛苦性检查方法,提倡不作首选。超声与CT结合检查,可相互取长补短,提高诊断水平,可取代ERCP和PTC检查。 |
| 英文摘要: |
| The imaging results of 25 cases of congenital cholodochal cysts are classified into three types.These three types are intrahaptic,extrahaptic and intra-extrahaptic.In the intrahaptic type,the porta branches are surrounded by the cystic dilatation ducts and together these have the specific appearance of a circle with a bright or dark central spot in contrast enhanced CT and CT-ductgraphy,respectively.The appearance of mural nodules in the cystic dilatation duct of the extrahaptic type is an indication of malignant change.This disease is 100% visualized in CT images.The diagnostic effectiveness of other imaging modalities:Ultrasonography has high diagnostic value;x-ray ductgraphy has little diagnostic effectiveness; ERCP and PTC are more effective,however,these methods are invasive and should not be the radiologist's first choice of imaging modelity.The authors consider the use of a combination of CT imaging and ultrasonography will raise the effectiveness of the diagnosis of this disease to the level where it may eventually replace examination by ERCP or PTC. |
