摘　　要：目的探讨卵巢浆液性囊性腺纤维瘤的磁共振（MRI）特征表现及病理学基础，提高对该病的诊断水平。方法回顾性分析经病理证实的21例卵巢浆液性囊性腺纤维瘤患者的MRI影像资料，所有患者术前均行MR平扫及增强扫描，对病灶内部结构、信号特征及增强表现进行分析。结果2例患者为双侧发病，19例为单侧发病，共23个病灶。病灶最大经为33～159mm，平均82．7mm；7个为囊实性，16个为囊性，其中单囊4个，多囊12个，有6个含有壁结节。所有病灶囊壁、分隔及实性成份在MRI—T2WI呈低信号，5个囊内壁局部增厚，呈“地毯征”；4个囊实性病灶中实性成份见小囊样高信号影，形成“黑色海绵征”。增强扫描17个病灶实性成份及囊壁呈轻中度强化，6例末见强化。结论卵巢浆液性囊性腺纤维瘤中囊壁及实性成份T2WI呈低信号，增强扫捕大部分呈轻中度强化；“地毯征”及“黑色海绵征”是其特征表现。Objective To explore the magnetic resonance （MRI） of ovarian serous cystadenofibromas based features and pa- thology, and to improve the level of diagnosis of the disease. Methods A retrospective analysis of MRI image data of pathologically confirmed 21 patients with ovarian serous cystadenofibromas was conducted. All patients underwent MR plain scan and en- hanced scan, the lesions of the internal structure, signal and enhancement were analyzed. Results There were 2 patients with bilateral disease, 19 cases of unilateral disease, a total of 23 lesions. The maximum lesion was 33 -159 mm, average 82.7 mm; 7 cases appeared as cystic and solid mixed masses, and 16 cases appeared as cystic lesions ,including 4 cases of single cyst and 12 cases of multilocular cysts, 6 with mural nodules. All lesions were cystic wall, septa and solid components showed low signal on MRI-T2WI, 5 cystic wall thickening, a ＂carpet sign＂ ; 4 cystic solid lesions in the solid component were seen capsule like high signal intensity, the formation of ＂black sponge sign＂. On enhanced scan, 17 lesions were solid component and the capsule wall was mild to moderate enhancement, 6 cases showed no enhancement. Conclusion Ovarian serous cystadenofibromas in the cystic wall and solid component T2WI showed low signal, enhanced scan showed mild to moderate enhancement most; ＂carpet sign＂ and ＂black sponge sign＂ are the characteristic expression.
