子宫腺肌症的MRI诊断

MRI Diagnosis of uterine adenomyosis

目的分析子宫腺肌症的MRI表现及其诊断价值。方法回顾分析26例经手术病理证实的子宫腺肌症患者的MRI资料,并与术后病理学结果进行对照分析。结果 MRI检查结果与手术病理结果高度一致。其中,弥漫性子宫腺肌症10例,在T2WI上表现为子宫结合带弥漫性增厚。局限性子宫腺肌症16例,在T2WI上表现为与结合带信号相近的低信号肿块影,边界模糊。本组26例低信号病灶,病理学上为增生肥大的平滑肌,其内散在的点状高信号灶为异位内膜岛。结论 MRI对子宫腺肌症的定性和定位具有很高的诊断价值。并在鉴别诊断中有着重要作用。

Objective To study the MRI features and its diagnostic value of uterine adenomyosis.Methods MRI features of 26 cases of uterine adenomyosis proved by surgery and pathology were reviewed and correlated with manifestations.Results MRI and pathology were highly consistent.ten diffuse uterine adenomyosis showed diffusely thickened junctional zone（JZ）on T2WI.Sixteen focal uterine adenomyosis displayed hypo-intensive masses like the intensity of JZ on T2WI.The hypo-intensive lesions in 26 cases corresponded to the hyperplastic and hypertrophic musculature,and the hyper-intensive foci within the hypo-intensive lesions were the heterotopic endometrial islands.Conclusion MRI is a very helpful modality in the diagnosis and localization of adenomyosis.It is very useful in the diagnosis and differential diagnosis.
