Sex cord-stromal tumors including granulosa cell tumor, thecoma, Sertoli stromal cell tumor and steroid cell tumor are noted for their hormonal activity. However, there are many kinds of ovarian tumors other than sex cord-stromal tumors and tumor-like conditions with endocrine manifestations. Cross-sectional imaging, especially MR, can provide precise features of ovarian tumors and uterine morphological change even in a clinically latent excess of estrogen. In this article, we demonstrate typical imaging findings of ovarian tumors with hormonal activity. We also shortly explain the mechanism of the virilization and hyperestrogenism caused by ovarian tumors and tumor-like conditions.
性索间质肿瘤，包括颗粒细胞瘤、卵泡膜瘤、支持间质细胞瘤和类固醇细胞瘤，以其激素活性而闻名。然而，除了性索间质肿瘤外，还有许多其他类型的卵巢肿瘤以及具有内分泌表现的肿瘤样病变。横断面成像，尤其是磁共振成像（MR），即使在临床上隐匿性雌激素过多的情况下，也能提供卵巢肿瘤的精确特征以及子宫形态变化。在本文中，我们展示了具有激素活性的卵巢肿瘤的典型影像学表现。我们还简要解释了卵巢肿瘤和肿瘤样病变引起男性化和雌激素过多的机制。
