巨大浆膜下子宫肌瘤的CT诊断与鉴别诊断

目的:总结15例巨大浆膜下子宫肌瘤(GSH)的CT表现,以期提高其诊断与鉴别诊断的准确性。方法:回顾性分析经手术病理证实的15例GSH,所有患者均行CT平扫及增强扫描,并将CT表现与手术病理结果对照。结果:GSH可表现为非均质实性(11例)、均质实性(3例)、囊实混合性(1例)3种类型,其中7例呈非均质实性的GSH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例呈非均质实性的GSH增强后呈“漩涡状”混杂密度,3例GSH瘤体边缘见低密度带。结论:GSH的CT表现有一定的特征性,其鉴别诊断主要应注意与原发性肠系膜肿瘤及胃肠道间质瘤鉴别。

CT Diagnosis and Differential Diagnosis of Giant Subserous Hysteromyoma

Objective To summarize the CT findings of giant subserous hysteromyoma in 15 cases,to improve its diagnostic accuracy.Methods 15 cases of giant subserous hysteromyoma proved by surgery and pathology were reviewed.CT plain scanning and enhanced scanning were performed in all cases.Results The lesions were presented as inhomogeneous solid(n=11),homogeneous solid(n=3),cystic-solid(n=1).after enhanced scanning,inhomogeneous solid hysteromyoma were consisted of multiple nodules and the septa which were appeared as linear structures(n=7);the vortex-like mixed density area were shown within the inhomogeneous solid hysteromyoma(n=4),the peritumor rim appered as low density in hysteromyoma(n=3).Conclusion CT findings of giant subserous hysteromyoma are characteristic to some extent,it should be paid special attention to distinguish giant subserous hysteromyoma from primary mesenteric tumors and gastrointestinal stromal tumors.
