目的：探讨卵巢纤维瘤的磁共振成像特征，强调纤维瘤同侧卵巢的存在和形态。材料和方法：两位放射科医生回顾了23例经组织学证实的卵巢纤维瘤患者的MR图像。11人处于绝经前，12人处于绝经后。在t2加权MR图像上评估纤维瘤同侧卵巢组织的存在和形状。结果：在24例卵巢纤维瘤中，有11例（46%）在t2加权图像上检测到同侧卵巢。11例纤维瘤中6例（55%）卵巢沿纤维瘤外围呈月牙形，5例（45%）卵巢呈正常椭圆形。在这5个肿瘤中，3个肿瘤的卵巢通过蒂状结构与纤维瘤相连，2个肿瘤的卵巢与纤维瘤的周围紧密相连。绝经前患者12例纤维瘤中有10例（83%）检测到同侧卵巢，绝经后患者12例纤维瘤中有1例（8%）检测到同侧卵巢。绝经前和绝经后妇女同侧卵巢的检出率差异有统计学意义（p = 0.001）。结论：MRI检查发现纤维瘤同侧剩余卵巢并不罕见，尤其是绝经前妇女，卵巢外周外生性生长纤维瘤的卵巢形态可能正常。(C) 2007年英国皇家放射学院。Elsevier Ltd.出版。版权所有。
AIM: To evaluate the magnetic resonance (MR) imaging features of ovarian fibromas, emphasizing the presence and shape of the ovary on the same side of the fibroma.MATERIALS AND METHODS: MR images from 23 patients with 24 histologically proven ovarian fibromas were reviewed by two radiologists. Eleven were pre-menopausal and 12 were postmenopausal. The presence and shape of the ovarian tissue on the same side of the fibroma were evaluated on T2-weighted MR images.RESULTS: In 11 (46%) of the 24 ovarian fibromas, the ipsilateral ovary was detected on T2-weighted images. The ovary was crescent-shaped along the periphery of the fibroma in six (55%) of 11 fibromas and had a normal, oval shape in five (45%). Of these five tumours, the ovary was connected to the fibromas by a pedicle-like structure in three and was closely attached to the periphery of the fibromas in two. The ipsilateral ovary was detected in 10 (83%) of 12 fibromas in pre-menopausal patients, and in one (8%) of 12 fibromas in postmenopausal patients. There was a statistically significant difference (p = 0.001) in the presence of detectable ipsitateral ovary between pre-menopausal and postmenopausal women.CONCLUSIONS: Detection of the remaining ovary on the same side as the fibroma is not unusual on MRI, especially in pre-menopausal women, and the shape of the ovary may be normal in cases of fibromas with exophytic growth from the periphery of the ovary.
