摘　　要：目的探讨卵巢(囊性)腺纤维瘤的MRI表现特征,提高对该病的认识。方法回顾性分析我院收治的23例经病理证实的卵巢(囊性)腺纤维瘤的MRI表现及临床资料。结果23例卵巢病例中,共26个病灶,均为浆液性,其中腺纤维瘤12个,囊性腺纤维瘤14个。发生于卵巢19个,卵巢冠7例。3例为双侧病灶,余均为单侧病灶。23例患者中囊性17例,囊实性病灶4例,实性2例。2例囊性均表现为单纯囊性,1例囊壁略厚,余为纤薄囊壁,囊壁呈等T1稍短T2信号影,囊内呈长T1长T2信号影,增强后囊壁可呈环状强化,囊内未见明显强化;另15例囊性表现为典型大囊并囊壁内斑点状及簇状短T2信号影,增强后囊壁及分隔轻度强化,囊内短T2信号不强化或轻度强化,B超可见囊壁可见点片状高回声,部分可及少许血流,4例囊实性成分表现复杂,其中3例表现为典型黑色海绵征,即病灶主要呈短T2信号影,其内可见多发小囊状高信号影;2例实性肿块呈长T1极短T2信号影,其中1例增强扫描后呈轻度不均匀强化。结论卵巢(囊性)腺纤维瘤表现复杂多变,多数表现为囊壁下簇状或点状突起的典型MRI表现,亦可见黑海绵征,提高对该病的认识,有助于更加精准的为临床治疗方案提供依据。Objective To explore the MRI features of ovarian(cystic)adenofibroma and improve understanding of the disease.Methods A retrospective analysis was conducted on the MRI findings and clinical data of 23 cases of pathologically confirmed ovarian(cystic)adenofibroma admitted to our hospital.Results Among the 23 ovarian cases,there were a total of 26 lesions,all of which were serous,including 12 adenofibromas and 14 cystic adenofibromas.Occurred in 19 ovaries and 7 cases of ovarian crown.Three cases were bilateral lesions,while the rest were unilateral lesions.Among the 23 patients,there were 17 cases of cystic lesions,4 cases of cystic solid lesions,and 2 cases of solid lesions.Two cases of cystic lesions were presented as simple cystic lesions,with one case having a slightly thick cyst wall and the remaining having a thin cyst wall.The cyst wall presented as a slightly shorter T2 signal shadow with equal T1,while the cyst interior presented as a long T1 and T2 signal shadow.After enhancement,the cyst wall could show circular enhancement,but no significant enhancement was observed inside the cyst;Another 15 cases showed typical large cysts with punctate and clustered short T2 signal shadows on the cyst wall.After enhancement,the cyst wall and septum were slightly enhanced,and the short T2 signal inside the cyst was not enhanced or slightly enhanced.B-ultrasound showed patchy hyperechogenicity on the cyst wall,with some blood flow visible.Four cases had complex cystic solid components,of which three cases showed typical black sponge sign,where the lesion mainly presented as short T2 signal shadows and multiple small cystic high signal shadows were visible inside;Two cases of solid masses showed long T1 and very short T2 signal shadows,of which one case showed mild uneven enhancement after enhanced scanning.Conclusion Ovarian(cystic)adenofibroma presents with complex and variable manifestations,mostly presenting as typical MRI features of clustered or punctate protrusions under the cyst wall,as well as black sea sponge
