摘　　要：目的：探讨外突浆膜下子宫肌瘤的ＣＴ特点及其鉴别诊断。方法：选取瘤体的３／４以上突出于子宫轮廓之外的１６例浆膜下子宫肌瘤为本组病例，共有１７枚瘤体。结果：１４／１７（８２．４％）枚瘤体的轮廓与子宫的轮廓相连续，１０／１７（５８．８％）枚瘤体内可见变性低密度区且均位于瘤体中心区或呈同心圆状分布，７／１０（４１．２％）枚瘤体内见“旋窝状”混杂密度影，５／１７（２９．４％）枚瘤体边缘见低密度带。结论：外突浆膜下子宫肌瘤的ＣＴ表现具有一定特征，其鉴别诊断尤应注意区别向子宫体两侧外突的肌瘤与卵巢肿瘤。Objective:To study CT characteristics and differential diagnosis of outprojecting subserous uterine myoma.Methods:17 outprojecting subserous myomas of 16 patients,of which 3/4 of tumor body projected out of the uterus proved by operation, were reviewed.Results:The border of myomas in 14/17(82.4%) continued with that of the uterus. Degenerative low density area in 10/17(58.8%) myomas was located in central area of myoma or appeared as a concentric circle.The vortex-like mixed density area was shown within the myomas in 7/17(41.2%).The peritumor rim appeared as low density in 5/17(29.4%).Conclusion:Outprojecting subserous uterine myoma has some CT characteristics. Special attention should be paid to distinguish bilaterally outprojecting subserous uterine myoma from ovarian tumor.
