BACKGROUND
Uterine torsion is defined as the rotation of more than 45 degrees around the long axis of the uterus. An uncommon but potentially fatal event, uterine torsion is rarely diagnosed until the time of surgery. With magnetic resonance imaging (MRI), however, an accurate diagnosis of uterine torsion may now be made preoperatively.
CASE
We describe a patient with uterine torsion in whom the correct diagnosis was made prenatally with the use of MRI, by the demonstration of an X-shaped configuration of the upper vagina.
CONCLUSION
Distinctive features suggestive of uterine torsion were demonstrated by MRI and enabled an accurate preoperative diagnosis. To our knowledge, this is the first reported case of uterine torsion diagnosed on MRI.
背景
子宫扭转定义为子宫围绕其长轴旋转超过45度。子宫扭转是一种罕见但可能致命的事件，直到手术时才很少被诊断出来。然而，借助磁共振成像（MRI），现在可以在术前准确诊断子宫扭转。
病例
我们描述了一名子宫扭转患者，通过磁共振成像显示上阴道呈X形结构，在产前做出了正确诊断。
结论
MRI显示了提示子宫扭转的独特特征，从而实现了术前准确诊断。据我们所知，这是首例通过MRI诊断子宫扭转的报道病例。
