【摘要】 目的探讨女性盆腔中不同组织学来源的巨大囊性肿块的CT相对特征。资料与方法回顾性分析48例经手术病理证实的女性盆腔囊性肿块(直径>10cm)的CT平扫及增强影像特征。结果 48例中,囊腺瘤18例,成熟型囊性畸胎瘤5例,交界性囊腺瘤4例,囊腺癌、肾脏囊肿、平滑肌瘤并黏液变性、淋巴管瘤各3例,颗粒细胞瘤、混合型生殖细胞瘤各2例,转移性腺癌、血管淋巴管瘤、无性细胞瘤、副中肾管残留囊肿、来源不明良性囊肿各1例。其中卵巢来源36例,占75.0%;生物学行为相对良性35例,占72.9%。26例(54.2%)囊壁规则,见于囊腺瘤、肾囊肿、淋巴管瘤、副中肾管囊肿、组织来源不明良性囊肿;无明确囊壁5例,见于血管淋巴管瘤、平滑肌瘤黏液变性、生殖细胞瘤;7例壁结节,见于卵巢浆液性乳头状囊腺瘤、黏液性囊腺瘤、囊性畸胎瘤和幼年型颗粒细胞瘤。囊内有分隔者22例(45.8%),均来源于卵巢,其中分隔规则9例,见于良性和交界性囊腺瘤;不规则13例,见于黏液性囊腺瘤、囊腺癌、混合型生殖细胞瘤、无性细胞瘤、颗粒细胞瘤和转移性肿瘤。脂肪成分见于5例畸胎瘤;钙化见于4例畸胎瘤和1例血管淋巴管瘤;实质成分明显8例,见于血管淋巴管瘤、平滑肌瘤黏液变性、生殖细胞瘤和颗粒细胞瘤。结论盆腔巨大囊性肿块组织来源及病理学类型较多,以卵巢来源居多,生物学行为良性比例较大,恶性多来源于卵巢,各种病理学类型之间有相对特异性CT特征,对于鉴别诊断具有意义。更多还原

【Abstract】 Objective To explore the CT features of the giant cystic masses in female pelvis.Materials and Meth-ods CT findings of 48 giant pelvic cystic masses(over 10 cm)confirmed by surgery and pathology were retrospectively analyzed.Results Those tumors included cystadenoma(18 cases),cystic teratoma(5 cases),borderline cystadenoma(4 case),cystadenocarcinoma(3 case),renal cyst(3 cases),leiomyoma with mucous degeneration(3 cases),lymphangioma(3 case),granulosa cell tumor(2 cases),mixed germ cell tumor(2 cases),Krukenberg tumor(1 case),hemangiolymphangioma(1 case),dysgerminoma(1 case),Wolffian cyst(1 case),undefined cyst(1 case).Tumors of 36 cases originated from ovary and accounted for 75.0%;benign tumors(35 cases)accounted for 72.9%.Regular cystic wall(26 cases,54.2%)were found in cystadenoma,renal cyst,lymphangioma,Wolffian cyst and benign undefined cyst;5 cases including hemangiolymphangioma,leiomyoma with mucous degeneration and mixed germ cell tumor had no well-defined cystic wall;papillary projections(7 cases)were in serous cystadenoma,mucious cystadenoma and juvenile type granulosa cell tumor;fat(5 cases)were in cystic teratoma;calification(4 cases)were in cystic teratoma and hemangiolymphangioma;soft-tissue component(8 cases)were in mixed haemangioma and lymphangioma,leiomyoma with mucous degeneration and germ cell tumor and granulosa cell tumor.Conclusion Giant cystic masses of female pelvis have various origins and types of pathology.CT is a valuable means for those tumors.There are some distinctive CT features among each type of tumors.更多还原
