摘　　要：目的探讨卵巢(囊)腺纤维瘤的MRI特征,以提高该病的诊断水平.方法回顾性分析18例经手术证实的卵巢腺纤维瘤(OAF)及卵巢囊腺纤维瘤(OCAF)患者的临床特征及MRI表现.结果18例患者共19个肿瘤,双侧卵巢1例,单侧17例(左侧卵巢9例和右侧卵巢8例).最大肿瘤长径17 cm,最小肿瘤直径0.6 cm.OAF 5例,其中1例OAF合并畸胎瘤的碰撞瘤.OCAF 13例,单囊7例和多囊6例,包括浆液性10例、黏液性1例及内膜样2例.囊性部分无强化,实性部分及囊壁结节呈T2 WI低信号,轻度强化,动态增强呈缓慢流入型.无盆腔积液及淋巴结转移.结论卵巢(囊)腺纤维瘤具有复杂的MRI表现.不同比例的囊腔与纤维间质是肿瘤的影像学基础,"蜂窝征"及"地毯征"是该组肿瘤较可靠的MRI特征.Objective To investigate the MRI features of ovarian adenofibroma(OAF)and ovarian cystadenofibroma(OCAF),and to improve the diagnosis ability.Methods The clinical features and MRI findings of 18 patients with OAF or OCAF confirmed by pathology were analyzed retrospectively.Results There were 19 tumors in 18 patients(bilateral tumors in 1 patient),9 in the left ovary and 8 in the right ovary.The diameter of the largest tumor was 17 cm and the smallest was 0.6 cm.5 patients were diagnosed as OAF,and 1 patient was collision tumor complicated with teratoma.13 patients were diagnosed as OCAF,including 10 with serous cystadenofibroma,1 with mucinous cystadenofibroma,and 2 with endometrioid cystadenofibroma.There were 7 patients with single cyst and 6 patients with multiple cysts.MRI showed the cystic part with no enhancement,the solid part and nodules in the cystic wall with low T2 WI signal and slight enhancement.Dynamic-contrast enhancement curve presented slow inflow.There were no pelvic cavity effusion and lymphatic metastasis.Conclusion The MRI features of OAF and OCAF are complicated.The varied proportions of cystic cavity and fibrous stroma are the imaging basis of the tumors.The Honeycomb sign"and Carpet sign"are reliable features of the tumors.
