摘　　要：目的探讨MRI在诊断卵巢蒂扭转中的应用价值。方法回顾性分析13例经手术病理证实的卵巢蒂扭转患者的MRI表现特点,提高对本病的认识。结果本组13例中,原发性卵巢蒂扭转3例;继发性卵巢蒂扭转10例:卵巢单纯性囊肿5例,卵巢巧克力囊肿2例,卵巢浆液性囊性腺纤维瘤、卵巢卵泡膜纤维瘤及卵巢畸胎瘤各1例。MRI均表现为盆腹腔区异常信号肿块。肿块局部与一侧宫角及附件相连12例,另1例为2月婴儿,子宫显示不清。扭转的卵巢蒂呈典型结节征(或漩涡征)5例,悬挂征4例,三角征4例。合并盆腔积液6例,妊娠1例,子宫肌瘤1例,对侧卵巢巧克力囊肿1例。结论卵巢蒂扭转的MRI表现具有一定特征,是超声等检查的有益补充。Objective To investigate the diagnostic value of magnetic resonance imaging （MRI） for ovarian pedicle tor-sion .Methods 13 cases of ovarian pedicle torsion confirmed by surgery pathology were reviewed retrospectively ,so as to improve the knowledge of it .Results In 13 cases ,there were primary ovarian torsion （n=3） and secondary ovarian tor-sion （n=10） .The secondary ovarian torsion included simple ovarian cyst （n=5） ,ovarian chocolate cyst （n=2） ,ovarian serous cystic fibroid （n=1） ,ovarian theca fibroma （n=1） ,and ovarian teratoma （n=1） .MRI demonstrated abnormal masses in abdominal area in 13 cases .It connected with one side uterine horn and accessories in 12 cases of masses .1 in-fant of 2 month could not provide a clear imaging of the uterine .The ovarian pedicle torsion presented typical “whirlpool sign” （n=5） ,“suspension sign” （n=4） ,and“triangle sign” （n=4） .It complicated with pelvic effusion （n=6） ,gesta-tion （n=1） ,fibroid （n=1） and chocolate cyst of contra-lateral ovary （n=1） .Conclusion MRI performances of ovarian pedicle torsion have certain characteristics .MRI examination is a beneficial supplement to ultrasound .
