卵巢囊腺瘤的CT诊断

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。

CT Diagnosis of Ovarian Cystadenoma

Objective:To improve the ability of CT diagnosis and differential diagnosis of ovarian cystadenoma.(Methods:)27 cases of ovarian cystadenoma proved by surgery and pathology were studied retrospectively.Results: Of 27(ovarian) cystadenomas,5 cases were serous,with homogenous density,uneven wall thickness,being unilocular(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 cystadenomas,6 cases were multilocular 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.
