摘要
目的探讨妊娠期附件扭转(AT)MRI表现及临床特点。方法回顾性分析14例经病理证实的妊娠期AT患者的MRI表现及临床资料。结果14例AT中,原发性2例,继发性12例(卵巢囊肿5例、卵巢畸胎瘤4例、输卵管积水2例、输卵管间皮囊肿1例);右侧5例,左侧9例;扭转角度180°~1720°。MRI示,除3例孤立性输卵管扭转外,其余11例均见卵巢增大,12例于盆腔或腹腔内见异常信号肿块,包括8例囊性肿块、4例囊实性肿块;肿块旁见扭转蒂7例,其中6例呈“鸟嘴征”,1例旋涡征,DWI均呈混杂高信号;附件出血6例,盆腔积液8例。6例孕妇分娩足月健康胎儿,8例分娩早产儿。结论妊娠期AT的MRI表现有一定特征性,结合临床特点有助于诊断。
Objective To explore MRI findings and clinical characteristics of adnexal torsion (AT) in pregnancy. Methods Clinical and MRI data of 14 patients in pregnancy with pathologically confirmed AT were retrospectively analyzed. Results There were 2 cases of primary AT and 12 cases of secondary AT (5 with ovarian cyst, 4 with ovarian teratoma, 2 with hydrosalpinx and 1 with tubal mesothelial cyst). AT occurred on the right side in 5 cases and on the left in 9 cases, with torsion angles ranged from 180° to 1 720°. MRI showed that except for 3 cases of solitary AT, ovarian enlargement occurred in 11 cases. Mass in pelvic or abdominal cavity was found in 12 cases, including 8 cystic masses and 4 cystic solid masses. The torsional pedicle next to the masses presented typical "beak sign" in 6 cases, while 1 case showed whirlpool sign, all showed mixed high signal in DWI. Adnexal hemorrhage was noticed in 6 cases and pelvic effusion in 8 cases. The pregnancy outcome was 6 full-term healthy fetuses and 8 preterm infants. Conclusion MRI findings of AT in pregnancy have certain characteristics, which are helpful to diagnosis of AT combined with clinical manifestations.
