目的探讨“尾征”在Dandy-Walker畸形诊断中的价值。方法对2013年5月至2014年9月间31例妊娠24周前行二线超声检查的胎儿进行了磁共振检查。结果MRI诊断Dandy-Walker畸形15例，部分尾部发育不全6例，蠕虫发育不全2例，蠕虫旋转不良4例，Walker-Warburg综合征2例，Blake囊囊肿1例，斜方脑融合1例。所有数据与胎检结果、30周后胎儿MRI或产后MRI进行比较；随访取决于母亲终止或继续妊娠的决定。在我们的复习研究中，我们发现了“尾征”的存在，这一征象仅见于Dandy-Walker畸形和Walker-Warburg综合征。结论“尾征”有助于Dandy-Walker、蠕虫旋转不良、蠕虫发育不良和蠕虫部分发育不全的鉴别诊断。(C)2015年John Wiley&Sons，Ltd.
Objective The study aims to demonstrate the value of the 'tail sign' in the assessment of Dandy-Walker malformation.Methods A total of 31 fetal magnetic resonance imaging (MRI), performed before 24 weeks of gestation after second-line ultrasound examination between May 2013 and September 2014, were examined retrospectively. All MRI examinations were performed using a 1.5 Tesla magnet without maternal sedation.Results Magnetic resonance imaging diagnosed 15/31 cases of Dandy-Walker malformation, 6/31 of vermian partial caudal agenesis, 2/31 of vermian hypoplasia, 4/31 of vermian malrotation, 2/31 of Walker-Warburg syndrome, 1/31 of Blake pouch cyst and 1/31 of rhombencephalosynapsis. All data were compared with fetopsy results, fetal MRI after the 30th week or postnatal MRI; the follow-up depended on the maternal decision to terminate or continue pregnancy. In our review study, we found the presence of the 'tail sign'; this sign was visible only in Dandy-Walker malformation and Walker-Warburg syndrome.Conclusion The 'tail sign' could be helpful in the difficult differential diagnosis between Dandy-Walker, vermian malrotation, vermian hypoplasia and vermian partial agenesis.
