11、, lungs or transfer the shadow can be diagnosed as aggressive PuTaoTai .有葡萄胎病史，并在第2次清宫后 8 12 周，HCG 未降至正常，有不规则阴道流血或影像学检查提示肿块侵犯子宫肌层，或肺部有转移阴影者可诊断为侵袭性葡萄胎 hydatidiform mole after the qing dynasty palace, H CG has been reduced to a normal period of time, and the symptoms appear HCG and rise or lungs, diag

12、nosis for aggressive transfer PuTaoTai; And no histological examination, above 1 years who happened to choriocarcinoma .葡萄胎清宫后，H CG已降至正常水平一段时间，又出现症状及HCG 升高或肺部有转移，诊断为侵袭性葡萄胎；而无组织学检查， 1年以上发生者为绒毛膜癌。 All that abortion, ectopic pregnancy, postpartum term anomalies H CG rising malignant GTN, general diagno

13、sis of flocking carcinoma. But if GuaGong pathological examination after see ShuiPaoZhuang organization or biopsy see fluff, still the diagnosis of aggressive PuTaoTai凡流产、宫外孕、足月产后出现异常H CG升高的恶性GTN，一般诊断为绒癌。但若刮宫后病理检查见水泡状组织或组织切片见到绒毛者，仍诊断为侵袭性葡萄胎瘤7妊娠滋养细胞疾病讲解GTD clinical diagnosis standarMR Imaging （葡萄胎）Th

14、e volume, and uterine cavity expansion, expand its note the amount of relatively uniform space capsule and a long T1, T2 signal, and long change nourish cell hyperplasia, with edema, formed the blister size differ about子宫体积扩大，子宫腔扩大，其内可见大量较均匀的分隔和小囊呈长T1、长T2信号改变，与滋养细胞增生，绒毛间质水肿，所形成大小不等的水泡有关 The soft tis

15、sue mass of uterine cavity, a typical honeycomb, or grapes. form, and by the formation of the water- blister structure arrangement about state宫腔内的软组织肿块影，呈典型“蜂窝”状或“葡萄”状，与所形成的水泡状结构排列状态有关 8妊娠滋养细胞疾病讲解MR Imaging （葡萄胎）The volume, a妊娠滋养细胞疾病讲解培训课件MR Imaging （葡萄胎） DWI high b value in that honeycomb mass, or

16、grapes. shape structure spread not limited with pathological changes, low degree of malignant cells are arranged, not too crowded, water molecules spread a smooth relevant DWI高b值时显示肿块内“蜂窝”状或“葡萄”状结构扩散不受限，与病变恶性程度低，细胞排列不太密集，水分子扩散较顺畅有关10妊娠滋养细胞疾病讲解MR Imaging （葡萄胎） DWI high b vMR Imaging （葡萄胎）Enhance scan

17、ning performance for multiple relatively uniform space strengthening, solid component not strengthened, and the water- blister structure and expansion of the blood supply.增强扫描表现为多发较均匀的分隔强化，实性成分不强化，与扩张的水泡状结构缺乏血供有关。11妊娠滋养细胞疾病讲解MR Imaging （葡萄胎）Enhance scanni hydatidiform mole benign view of size differ

18、 in the blisters, microscopically nourish cells different degree, the hyperplasia edema, the increase in size, outline rules, interstitial inner tire source sex disappear blood vessels, but not involving uterine muscle layer .良性葡萄胎大体观为大小不等的水泡，镜下见滋养细胞不同程度增生，绒毛间质水肿，体积增大，轮廓规则，间质内胎源性血管消失，但未侵犯子宫肌层Patholo

19、gical characteristics （葡萄胎） 12妊娠滋养细胞疾病讲解 hydatidiform mole benign vieMR Imaging （恶性 GTD）Capsule incomplete soft tissue mass, can show, a “crumb also cellular”, or “grapes.” shape, it shows high signal with pathological changes, flake necrosis related 包膜不完整的软组织肿块，可呈团块状，亦可呈“蜂窝”状或“葡萄”状，其内可见片状高信号，与病变坏死相

20、关 Endometrial signal discontinuous mass, infringe upon womb jiceng, and uterine muscle layer boundary is not clear, is one of the most important features in GTD malignant子宫内膜信号不连续，肿块侵犯子宫肌层，与子宫肌层界限不清，是恶性GTD的重要特征之一 13妊娠滋养细胞疾病讲解MR Imaging （恶性 GTD）Capsule inMR Imaging （恶性 GTD）Uterine cavity mass and aro

26、 also depends on the clinical and pathological diagnosis MRI对于鉴别良性葡萄胎与侵袭性葡萄胎及绒癌较超声更佳，但对于侵袭性葡萄胎与绒癌的鉴别还有赖于临床及病理诊断 Still should identify with the following disease 还应与以下疾病鉴别 17妊娠滋养细胞疾病讲解Differential diagnosisMagneticDifferential diagnosisEndometrial carcinoma子宫内膜癌 :With endometrial uneven thickening sh

27、owing the endometrial signal irregular, discontinuous and tumor deep abnormal signals of infringement to give priority 子宫内膜癌以子宫内膜不均匀增厚所表现出的子宫内膜信号不规则、不连续和肿瘤向深部侵犯的异常信号为主 The characteristic of malignant GTD blood flow “empty” signal and more help to identify kitchen bleeding恶性GTD特征性的“血管流空”信号和多灶出血有助鉴别 T

28、he enhanced due to abnormal blood supply GTD malignant are very abundant, cause its abnormal strengthen than endometrial cancer.增强后由于恶性GTD异常血供非常丰富，造成其异常强化程度高于子宫内膜癌。 18妊娠滋养细胞疾病讲解Differential diagnosisEndometDifferential diagnosisAdenomyosis子宫腺肌症:The increased to different extent, smooth contour, some
