摘　　要：目的探讨卵巢Brenner瘤的CT表现,以提高对该病的认识和诊断水平。方法回顾分析8例经手术、病理证实的卵巢Brenner瘤患者的CT特征,并与病理结果进行对照。结果 8例中3例位于右侧,5例位于左侧,病变边界清楚,6例呈圆形或椭圆形,2例呈不规则或分叶状。其中实性病变4例,以实性为主,内见多发散在钙化影,增强后病灶中度强化;囊实性病变3例,CT表现为囊性与实性成分相互掺杂、成分相当,增强后实性部分明显强化,囊性部分未见明显强化;囊性病变1例,内见乳头状突起,增强后乳头状结节轻度强化。镜下肿瘤由上皮细胞巢和纤维间质组成,5例上皮巢中可见腺样囊腔,细胞无病理性核分裂相,8例病理诊断均为卵巢良性Brenner瘤。结论卵巢Brenner瘤的CT表现具有一定特征性,但特异性不高,最后诊断常需依靠病理证实。Objective To explore the computed tomography （CT） finding of ovarian Brenner tumor and improve the diagnosis and treatment of Brenner tumor. Methods CT imaging of 8 cases of ovarian Brenner tumor confirmed by operation and pathology examination were analyzed retrospectively and compared with pathological findings. Results Three of 8 lesions were located in right,5 in left. All these masses were well defined,6 appeared as round or oval,2 as irregular or lobulated shaped. Of 8 cases ,4 lesions presented solid masses, which showed soft tissue masses with multiple punctate irregular calcifications and moderate enhancement. 3 cases presented mixed cystic and solid masses, which had approximately equivalent cystic and solid components. The solid component of tumors showed marked enhancement while the cystic component showed no enhancement on post contrast images. One lesion presented a cystic masse, which had a papillation inside with mild enhancement. Pathologically, the tumors were composed of epithelial cell nests and fibrous stroma. In 5 cases adenoid cystic cavity in middle of the nest can been found. Without atypical ceils were seen in 8 cases so that they were diagnosed as ovarian benign Brenner tumor. Conclusion CT imaging of ovarian Brenner tumor has somewhat characteristic features, but it is not very specific, and the definitive diagnosis should relied on pathology.
