Ovarian cystadenofibroma is a benign ovarian tumor that is characterized by a consistent percentage of masses, which remain indeterminate in ultrasonography and require magnetic resonance (MR) investigation; they may mimic borderline or malignant lesions. Three main morphologic patterns, resembling different ovarian neoplasms, can be identified in cystadenofibromas: multilocular solid lesions, unilocular cystic lesions with parietal thickening, and purely cystic masses. However, a cystoadenofibroma has typical features, such as T2-weighted hypointensity associated with no restrictions in diffusion-weighted imaging (the so-called "dark-dark appearance") and progressive post-contrast enhancement (type I perfusion curve). The purpose of this study was to review the features of ovarian cystadenofibromas in MR imaging and to suggest pearls and pitfalls regarding their correct diagnosis.
卵巢囊腺瘤纤维瘤是一种良性卵巢肿瘤，其特征是一定比例的肿块在超声检查中仍不确定，需要磁共振（MR）检查；它们可能类似于交界性或恶性病变。在囊腺瘤纤维瘤中可以识别出三种主要的形态模式，类似于不同的卵巢肿瘤：多房实性病变、单房囊性病变伴壁增厚和单纯囊性肿块。然而，囊腺瘤纤维瘤具有典型特征，如 T2 加权像低信号，弥散加权成像（所谓的“黑暗-黑暗外观”）无受限，以及对比后渐进性强化（I 型灌注曲线）。本研究旨在回顾卵巢囊腺瘤纤维瘤的 MR 成像特征，并提出正确诊断的要点和陷阱。
