目的 探讨女性附件区肿瘤蒂 扭转的MRI影像学表现特点，提高MRI的 诊断符合率。方法 回顾性分析2012年11 月-2017年1月以来经我院手术病理证实 的35例附件区肿瘤蒂扭转的MRI、超声影 像资料，结合病理讨论其MRI表现特点。 结果 本组35例患者中，卵巢囊肿蒂扭 转共15例，卵巢囊腺瘤蒂扭转5例，畸胎 瘤蒂扭转7例，输卵管系膜囊肿蒂扭转 4例，单纯卵巢蒂扭转3例，浆膜下肌瘤 蒂扭转1例，畸胎瘤蒂扭转合并妊娠(28 周)1例，单纯卵巢蒂扭转合并输卵管血 肿1例(孕15周)，畸胎瘤蒂扭转伴甲状 腺、黄体血肿1例。增强扫描3例。MRI特 征性表现：附件区混合信号肿块，与子 宫一侧相连(100%，35/35)；肿块蒂部 显示(91.43%,32/35)，肿块蒂部漩涡征 (65.71%，23/35)，肿块近蒂部三角征 (65.71%,23/35)；囊肿壁近蒂部新月形、 弧形增厚(68.57%，24/35)，合并盆腔 积液(82.86%,29/35)。核磁诊断符合率 (85.71%,30/35)高于超声超声诊断符合率 (71.43%,25/35)。结论 女性附件区肿瘤 蒂扭转的MRI表现具有一定的特点，MRI具 有一定的诊断价值。

Objective To explore the MRI imaging features of tumor torsion in female attachment area, and to improve the diagnostic coincidence rate of MRI. Methods Retrospectively analyzed the MRI and ultrasonographic data of 35 cases of tumor pedicle torsion confirmed by surgical pathology in our hospital from November 2012 to January 2017, and discussed the MRI features of the tumor. Results The group of 35 patients, ovarian cyst torsion in 15 cases, ovarian cystadenoma torsion in 5 cases, teratoma torsion in 7 cases, tubal cystic torsion in 4 cases, 3 cases of simple ovarian pedicle torsion, 1 case of torsion of subserosal fibroids, 1 case of teratoma torsion with gestation (28 weeks), 1 case of simple ovarian pedicle torsion with tubal hematoma (15 weeks of gestation), teratoma torsion with thyroid, luteal hematoma in 1 case. MRI characteristic manifestation: attachment area mixed signal mass, connected with the uterus side (100%, 35/35); Mass pedicle display (91.43%, 32/35), Whirlpool sign (65.71%, 23/35), Triangular sign (65.71%, 23/35), cyst wall near the pedicle crescent-shaped, curved thickening (68.57%, 24/35), combined pelvic fluid (82.86%, 29/35). The coincidence rate of nuclear magnetic diagnosis (85.71%, 30/35) was higher than that of ultrasound ultrasound (71.43%, 25/35). Conclusion The MRI features of tumor pedicle torsion in female attachment area have certain characteristics, and MRI has some diagnostic value.
