摘要
目的:提高对卵巢囊腺瘤CT诊断及鉴别诊断能力。方法:回顾性分析手术病理证实的27例卵巢囊腺瘤的CT表现。结果:浆液性囊腺瘤5例,单房4例,多房1例,密度均匀,囊壁可薄可厚或厚薄不均。粘液性囊腺瘤9例,单房3例,密度均匀,囊壁厚,多房6例,密度不均匀,内见多发大小不等子囊。交界性(6例)和恶性变(7例)13例,其中浆液性3例,粘液性10例,12例为多房改变,囊壁及分隔增厚且边缘模糊,部分呈囊实性及壁结节改变,2例恶性变者伴有大量腹水。结论:单房浆液性囊腺瘤及多房粘液性囊腺瘤具有较典型CT表现,CT易于诊断及鉴别诊断,当病变呈囊实性改变,出现壁结节,或囊壁分隔不规则增厚模糊时,提示交界性或恶性变。
Objective： To improve the ability of CT diagnosis and differential diagnosis of ovarian cystadenoma. Methods：27 cases of ovarian eystadenoma proved by surgery and pathology were studied retrospectively. Results： Of 27 ovarian eystadenomas, 5 cases were serous, with homogenous density, uneven wall thickness, being uniloeular（n = 4） and multilocular （n =1 ）. 9 cases were mucous and 13 cases were borderline（n = 6） and malignant（n = 7）. In the 9 mucous eystadenomas,6 cases were multiloeular with inhomogenous density and multiple secondary cysts with inequality of size. In 13 cases of borderline or malignant transformation cystadenomas, 3 cases were serous, 10 cases were mucous; 12 cases were multilocular with protruding wall nodes, uneven wall thickness and/or septa,indistinct margin, partly cystic and solid area; 2 cases of malignant lesions with ponderous ascites. Conclusion：Unilocular and multilocular serous cystadenomas has typical CT signs for diagnosis and differential diagnosis. It is difficult to identify borderline cystadenoma. When cystic and solid area and/or protruding wall nodes,irregular thick wall and septa appear in the tumor,it usually suggests that borderline or malignant transformation exists.
