摘要
目的探讨MRI对恶性滋养细胞肿瘤的诊断价值。方法回顾性分析14例经临床手术病理证实的恶性滋养细胞肿瘤患者的MRI表现。结果 MRI表现为子宫不同程度增大,腔内肿块呈混杂信号影,7例肿瘤形态似"蜂窝"状或"葡萄"状,9例在肿块周围、子宫腔内及肌层可见增粗、迂曲流空血管影,6例宫旁两侧可见增多、迂曲血管影,增强扫描后9例病灶分隔及实性部分中度以上强化,其中6例呈早期明显强化,2例囊性病灶中央可见血管样强化的"血湖"状表现,3例显示病灶侵犯、突破浆膜层。结论恶性滋养细胞肿瘤MRI表现具有一定特征性,并可以很好的显示肿瘤侵犯范围,为临床诊断及治疗提供依据。
Objective To analyze the MRI appearancs of malignant trophoblastic tumors and to investigate the diagnostic value of MRI.Methods MRI findings in 14 patients with malignant trophoblastic tumors confirmed by clinic and surgical pathology were reviewed retrospectively .Results The uterus in all cases increased with varying degree on MRI , cavity lump was mixed sig-nals, 7 cases showed “honeycomb” and“grape” signal intensity , 9 cases showed grossus and tortuosity of the vessels around the mass and cavitary uteri and myometrium of uterus , 6 cases showed grossus and tortuosity of the vessels around uterus , 9 cases showed septal enhancement and the whole solid enhancement , 6 cases showed that part of the lesions were enhanced in the early phase, 2 cases showed intra-mass enhancement like “blood lake”, and 3 cases showed invaded serosa .Conclusion The malig-nant trophoblastic tumor lesions shows characteristic manifestationson on MRI and show the extent of the lesions very well , which can provide the basis for clinical diagnosis and treatment .
