摘　　要：目的:探讨巨大浆膜下子宫肌瘤(giant subserous hysteromyoma,GSH)的CT与MRI表现,以期提高诊断水平。方法:回顾性分析15例GSH的CT平扫、增强扫描及14例MRI平扫1、0例增强扫描表现并与手术病理结果对照。结果:5例CT表现呈非均匀实性的GSH在增强后内部呈多个大小不等的结节状改变,其间可见分隔结构,4例呈非均匀实性的GSH增强后呈"漩涡状"混杂密度,3例GSH瘤体边缘见低密度带。MRI T1WI所有肌瘤表现为等、低信号,T2WI表现为低或混杂信号,5例瘤体内部为结节状改变,其间可见高信号分隔结构,7例瘤体边缘见低信号带。结论:GSH的CT与MRI表现有一定的特征性,具有较高的诊断价值。Objective：To explore the CT and MPd findings of giant suhserous hysteromyoma（GSH） so as to improve diagnostic accura- cy.Methods： 15 eases of CT and MPd of giant suhserous hysteromyoma proved by surgery and pathology were reviewed. CT plain and en- hanced scanning were performed in all eases; MPd were performed in 14 eases, of which 10 eases were performed with contrast enhance- mere.Results：The lesions presented as inhomogeneous solid （n = 11）, homogeneous solid （n = 3）, cystic-solid （n = 1）. Solid hys- teromyoma appeared multiple nodules and the septa were inhomogeneous density after contrast enhancement （n = 7）, the vortex-like mixed demity area wereshown within the inhomogeneous solid hysteromyoma （ n = 4）, the pefitumor rim appeared as low density in hys- teromyoma （ n = 3）. All lesions presented as intermediate or low signal intensity on Tl-weighted images, low or heterogeneous signal in- tensity, 6 lesions were consisted of multiple nodules and the hyperintensity septa as linear structures, the pefitumor rim appeared as low signal intensity in 7 lesions. Condusion： CT findings of giant subserous hysteromyoma prtrvide some characteristics. It should be paid special attention to distinguish giant subserous hysteromyoma from primary mesentexic tumors and gastrointestinal stromal tumors.
