摘　　要：目的:探讨多层螺旋CT及图像后处理技术对卵巢肿瘤蒂扭转的诊断价值。方法:回顾分析2010年1月-2019年12月我院经手术病理证实63例卵巢肿瘤蒂扭转的多层螺旋CT表现,提高对本病认识。结果:扭转的卵巢肿瘤包括单纯性囊肿19例,畸胎瘤20例,囊腺瘤9例,性索间质来源肿瘤14例,巧克力囊肿1例。右侧38例,左侧25例,肿瘤呈囊性32例,囊实性17例,实性14例。CT轴位及冠状位、矢状位MPR图像显示卵巢扭转的蒂61例,肿瘤壁新月形或环形增厚42例,肿瘤内出血19例,子宫向扭转侧移位34例,肿瘤壁表面毛糙19例,肿瘤周围脂肪炎性反应23例,盆腔积液、积血19例,4例患者见水肿卵泡征。结论:卵巢肿瘤蒂扭转具有特征性的CT影像学表现,CT轴位结合冠状位和矢状位MPR图像可明显提高卵巢肿瘤蒂扭转的准确率。Objective:To evaluate the diagnostic performance of MSCT and post-processing technique on the diagnosis of pedicle torsion of ovarian tumor(PTOT).Methods:Sixty-three cases with PTOT confirmed by surgery pathology in our hospitals from January 2010 to December 2019 were reviewed retrospectively,so as to improve the knowledge of it.Results:The twisted ovarian tumors included simple cyst 19 cases,teratoma 20 cases,serous/mucinous cystadenoma 9 cases,sex cord stromal tumor of ovary 14 cases,and chocolate cyst 1 case,there were 38 cases of right side,and 25 cases of left side.In the 63 cases,according to the CT imaging features,there were 32 cases of cystic mass,17 cases of cystic-solid mixed mass,and 14 cases of solid mass.Combine the CT axial with coronal and sagittal MPR images,the twisted pedicles of ovarian tumor were showed in 61 cases,crescent or annular thickening of tumor wall in 42 cases,internal hemorrhage in 19 cases,uterine displacement to torsion side in 34 cases,rough surface of tumor wall in 19 cases,inflammatory infiltration around tumor in 23 cases,pelvic effusion and hemorrhage in 19 cases,"follicular edema sign"in 4 cases.Conclusion:PTOT has typical characteristic CT imaging features,the accuracy rate can markedly improved by combine the axial with coronal and sagittal MPR images in the diagnosis of PTOT.
