SCT及MPR在卵巢囊肿蒂扭转中的诊断价值

目的探讨螺旋CT(spiral CT,SCT)及多平面重建(multi-planar reconstruction,MPR)技术对卵巢囊肿蒂扭转的诊断价值,提高对卵巢囊肿蒂扭转的认识。方法回顾性分析11例经手术病理证实的卵巢囊肿蒂扭转的临床资料、CT及MPR图像表现,并与手术病理对照分析。结果 11例CT均表现为卵巢囊性肿块,平均最大径为8.3cm。囊壁增厚8例,无增厚3例,增厚的囊肿壁呈非对称性,连续层面观察囊壁最厚处可见有条索状软组织密度的蒂部相连,并延伸至一侧附件或子宫角部,SCT的MPR能更清楚地显示蒂部这一特征性表现。7例腹盆腔积液。结论卵巢囊肿蒂扭转的CT表现有一定特征性,SCT及MPR在诊断卵巢囊肿蒂扭转中有很高的临床应用价值,其MPR可以任一平面重建图像,弥补了轴位CT图像的不足。

Value of SCT and MPR in diagnosis of pedicle torsion of ovarian cysts

【Objective】 To investigate the diagnostic value of SCT and MPR in pedicle torsion of ovarian cysts,and making a further understanding of this disease.【Methods】 The clinical data,SCT and MPR films manifestations of 11 pedicle torsion of ovarian cysts confirmed by surgery and pathology were retrospectively analyzed,and the results were compared with pathology.【Results】 The CT finding was an ovarian cystic mass,and the mean maximum diameter of it was 8.3 cm.8 cases had thickening walls,3 cases hadn’t.The thickening wall was asymmetric,and the greatest thickness parts of wall had a striped soft tissue density pedicle connecting with adnexa or uterine horn.MPR films could clearly show this characteristic of pedicle.7 cases had pelvic effusion or ascites.【Conclusions】 CT findings of pedicle torsion of ovarian cysts had some features.SCT and MPR techniques had high value in diagnosis of pedicle torsion of ovarian cysts.MPR could reconstruct images at any plane,so it could make up for the lack of axial CT scan.
