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。
Objective: To summarize the CT findings of 15 cases of giant submucous uterine fibroids (GSH) in order to improve the accuracy of their diagnosis and differential diagnosis. Methods: Fifteen cases of GSH confirmed by surgery and pathology were retrospectively analyzed. CT scan and contrast-enhanced scan were performed in all patients. The CT findings were compared with the pathological findings. Results: GSH showed heterogeneous solidity (11 cases), homogeneous solidity (3 cases) and cystic solidification (1 case). Among them, GSH increased in 7 cases with heterogeneous solidity There were a number of nodular changes in the internal size, showing a separation between the structure; 4 cases of heterogeneous solid GSH enhanced after the “whirlpool” hybrid density, 3 cases of GSH tumor edge of the low density band. Conclusion: The CT findings of GSH have certain characteristics. The differential diagnosis should be mainly associated with primary mesenteric tumors and gastrointestinal stromal tumors.
