目的:探讨卵巢卵泡膜细胞瘤的CT与MRI的影像学特点,旨在提高该病的影像诊断符合率。方法:回顾性分析经手术病理证实的7例卵巢卵泡膜细胞瘤的CT和MRI表现。结果:7例均为单侧肿块。CT为等密度肿块,5例密度均匀,2例密度不均匀。MRI以等低信号为主,T2WI伴不同程度的高信号。CT增强7例肿块均呈渐进性轻度强化。结论:卵泡膜细胞瘤的CT及MRI表现有一定的特征性,两者结合对诊断本病有重要价值。
Objective: To investigate the imaging features of CT and MRI in the treatment of ovarian follicular melanocytoma, aiming to improve the coincidence rate of imaging diagnosis of the disease. Methods: The CT and MRI findings of 7 cases of ovarian oncocytoma confirmed by surgery and pathology were analyzed retrospectively. Results: Seven cases were unilateral tumor. CT was isodense mass, 5 cases of uniform density, 2 cases of uneven density. MRI with low signal-based, T2WI with varying degrees of high signal. CT enhancement in 7 cases were progressive mild enhancement. Conclusion: The CT and MRI manifestations of theca cell tumor have certain characteristics. The combination of the two has important value in the diagnosis of this disease.
