【摘要】：目的探讨卵巢纤维卵泡膜细胞瘤的螺旋CT及磁共振成像(MRI)表现并与病理对照分析,旨在提高对本病的影像学诊断水平。方法回顾性分析25例经手术病理证实的卵巢纤维卵泡膜细胞瘤患者的螺旋CT及MRI表现。结果 25例患者共发现27个病灶,单侧23例,双侧2例;病灶形态呈类圆形、卵圆形16个,分叶状11个;CT平扫示实性肿瘤和囊实性肿瘤实性部分的密度略低于子宫肌层,增强扫描示肿瘤在动脉期和延迟期呈缓慢渐进性轻度强化;MRI扫描后肿块实性部分T1加权像呈等或稍低信号,T2加权像抑脂序列呈稍低或稍高信号,弥散加权像呈稍高信号,增强后强化特点同于CT。3例患者盆腔内可见少量积液。结论卵巢纤维卵泡膜细胞瘤具有一定的影像学特征,对提高本病的诊断及鉴别诊断水平、降低术前误诊率有重要的临床价值。
[Abstract]:Objective to investigate the spiral CT and magnetic resonance imaging (MRI) findings of fibrous follicular cell tumor of the ovary and to compare the findings with pathology. Methods the spiral CT and MRI findings of 25 patients with fibrous follicular cell tumor of ovary proved by surgery and pathology were analyzed retrospectively. The lesions were round in shape, 16 oval in shape and 11 in lobular shape. The density of solid part of solid tumor and cystic solid tumor was slightly lower than that of myometrium on plain CT scan. Contrast-enhanced imaging showed that the tumor showed slow and progressive mild enhancement in arterial phase and delayed phase. After MRI, the solid part of the tumor was on T 1 weighted images with equal or slightly low signal intensity and slightly high signal intensity on T 2 weighted imaging, and diffusion-weighted images showed slightly high signal intensity. Conclusion the enhancement features of ovarian fibrous follicular cell tumor have some imaging features, which can improve the diagnosis and differential diagnosis of this disease. It has important clinical value to reduce the misdiagnosis rate before operation.
