卵巢硬化性间质瘤CT诊断

CT Findings of Ovarian Sclerosing Stromal Tumor

目的:探讨卵巢硬化性间质瘤(SST)的CT表现。方法:回顾性分析3例经手术病理证实的卵巢硬化性间质瘤CT表现。结果:3例均为单发,肿瘤呈实性2例,囊实性1例。平扫肿块密度不均,动态增强扫描肿块边缘部分早期明显强化,延迟扫描呈持续性显著强化,2例实性肿块轻度向心性延迟强化,1例囊变区无强化。结论:SST动态增强扫描具有特征性强化表现,CT可提示本病的诊断。

Objective： To discuss the CT findings of ovarian sclerosing stromal tumor （SST）. Methods：CT findings in 3 patients with ovarian SST proved by surgery and pathology were retrospectively analyzed. Results： All of the three patients had solitary tumor. There were solid tumor （n= 1） and cystic-solid tumor （n= 2）. All lesions were heterogeneously attenuated on plain CT, marked marginal enhancement was showed in the early phase, and consistent significant enhancement in the delayed phase of dynamic contrast CT. Mild centripetal delay enhancement were showed in the two solid lesions, while no enhancement was assessed in the cystic area of the cystic-solid lesion. Conclusion：Certain characteristic findings could be assessed on dynamic contrast-enhanced CT,which provided diagnostic evidence for ovarian SST.
