卵巢颗粒细胞瘤影像诊断

目的:探讨卵巢颗粒细胞瘤的影像学特征。材料与方法:回顾性分析11例病理证实的卵巢颗粒细胞瘤的CT、MRI资料。结果:1 10例单发,其中左侧7例,右侧3例;1例双侧多发。8例圆形,边界清晰,3例分叶状,边界模糊。2 CT表现:5例不均匀实性肿块,伴小囊状或片状低密度区,分界清晰,1例呈蜂窝状;3例轻度强化,2例中度强化。3例为多房囊性肿块,囊壁和分隔厚薄不均,明显强化。3 MRI表现:5例囊实性肿块,呈蜂窝状,囊壁及分隔厚薄不一,明显强化。3例实性肿块,不均匀中度强化。1例囊性肿块,分隔及囊壁明显强化。结论:卵巢颗粒细胞瘤具有一定的影像学特征,综合分析其影像特征,结合临床及实验室检查,在术前可以做出正确诊断。

Imaging Diagnosis of Ovarian Granulosa Cell Tumor

Purpose： To investigate the imaging features of ovarian granulosa cell tumor（OGCT）. Materials and Methods： CT , MRI datas of 11 cases with OGCT proved by pathology were retrospectively analyzed. Results： ①10 cases were single, there were 7 cases at left and 3 cases at right ; 1 case was bilateral multiple, g cases were round with clear bound- aries, 3 cases were lobulated with fuzzy boundaries. ② CT manifestations： 5 cases were non-uniform solid masses with small cystic or flake low-density and clear boundaries, 1 case showed honeycomb. 3 cases slightly enhanced, 2 cases moderately enhanced. 3 case was multiple cystic mass, cyst wall and separated were uneven thickness and significantly enhanced. ③ MRI manifestations： 5 cases were cystic and solid masses with honeycomb, cyst wall and separated were uneven thickness and significantly enhanced. 3 cases were solid masses with encapsulated and uneven moderately enhanced. 1 case was cystic masses, cyst wall and separated significantly enhanced. Conclusion： OGCT had certain imaging features, combined withclinic and laboratory could make correct diagnosis before surgery.
