子宫肉瘤的MRI表现

目的探讨子宫肉瘤的MRI表现及特征,并与病理学对照,以提高对该类疾病的诊断及鉴别诊断能力。方法分析14例经病理证实的子宫肉瘤的MRI影像资料,其中10例行MRI平扫和增强,4例行MRI平扫。结果 6例为子宫内膜间质肉瘤,4例为平滑肌肉瘤,4例为癌肉瘤,14例均表现为子宫体积增大,宫腔内巨大软组织肿块影,病灶信号欠均匀,10例增强后分别呈中度或明显不均匀强化。结论 MRI平扫及动态增强扫描并结合临床资料可以提高对子宫肉瘤的正确诊断率,增强扫描可以准确判断肿瘤的解剖部位及对邻近组织的侵犯情况,但最终确诊仍需靠病理学检查。

MRI Imaging of Uterine Sarcomas

Objective To investigate MR imaging of uterine sarcomas, and with pathological control, in order to improve the capability of diagnosis and differential diagnosis. Methods MR imaging of uterine sarcomas in 14 cases proved by surgery and pathology were retrospectively reviewed. 10 cases were performed with MR routine and enhanced scan, and 4 case was performed with MR routine scan. Results Of the 14 patients, 6 cases were endometrial stromal sarcomas, 4 cases were leiomyosarcomas and 4 cases were malignant mixed mesodermal tumors. All the tumors were appeared as intrauterine huge soft tissue mass with heterogeneous signal intensity. 10 cases showed heterogeneous enhancement moderately or markedly. Conclusion Routine and dynamic contrast-enhanced MRI scans and clinical data can increase the rate of correct diagnosis of uterine sarcoma, enhanced scan is useful in defining accurately the location and extent of a lesion, but the definitive diagnosis can be made ultimately by pathological examination.
