【摘要】：目的探讨卵巢硬化性间质瘤(SST)的MRI表现和病理特征,并分析其影像学特点,以提高MRI对SST的诊断能力。资料与方法回顾性分析经病理证实为SST患者8例,分析其病灶形态、大小、信号及强化模式,并与病理形态学特点进行对比。结果 8例患者病灶均为边缘较清晰的单发囊实性包块,包膜完整。3例囊性者典型征象为"湖岛征",5例实性者中央可见"瘢痕样""星芒状"囊变区,MRI增强扫描病灶实性部分呈"海绵状血管瘤样"渐进性持续性强化,呈"快进慢出"特征,其囊性部分不强化。MRI表现与病灶形态、显微镜下假小叶结构及丰富的小血管等病理特点相符合。结论 SST的MRI表现具有一定的特征性,能较准确地反映其病理特点,有助于与卵巢其他肿瘤的鉴别诊断,为临床手术方式的选择提供客观依据。
[Abstract]:Objective to investigate the MRI findings and pathological features of ovarian sclerosing stromal tumor (SST) and to analyze its imaging features in order to improve the diagnostic ability of SST on MRI. Materials and methods 8 cases of SST proved pathologically were analyzed retrospectively. The morphology, size, signal and enhancement pattern of the lesions were analyzed and compared with the pathological features. Results the lesions in all the 8 patients were single cystic mass with clear margin. The typical signs of 3 cases with complete capsule were "Lake Island sign" and 5 cases of solid sex. "scar" and "starlike" cystic zone could be seen in the center of 5 cases. The solid part of the lesion was "cavernous hemangioma-like" progressive and persistent enhancement on MRI enhanced MRI. It was characterized by "fast entry and slow out", and its cystic part was not enhanced. MRI findings were consistent with pathological features such as lesion morphology, microscopically pseudobular structure and abundant small blood vessels. Conclusion the MRI findings of SST have some characteristics, which can accurately reflect the pathological features of SST, be helpful to the differential diagnosis of other ovarian tumors and provide an objective basis for the choice of clinical surgical methods.
