OBJECTIVE
The CT and MRI features of ovarian torsion are illustrated with gross pathologic correlation. Ovarian enlargement with or without an underlying mass is the finding most frequently associated with torsion, but it is nonspecific. A twisted pedicle, although not often detected on imaging, is pathognomonic when seen. Subacute ovarian hemorrhage and abnormal enhancement is usually seen, and both features show characteristic patterns on CT and MRI. Ipsilateral uterine deviation can also be seen.
CONCLUSION
Diagnostic pitfalls that may mimic ovarian torsion and observations for discriminating them are discussed.
目的
通过大体病理相关性，阐述卵巢扭转的 CT 和 MRI 特征。卵巢增大伴或不伴基础肿块是最常与扭转相关的发现，但不具有特异性。扭曲的蒂，尽管在影像学上不常被发现，但当被看到时是具有特征性的。亚急性卵巢出血和异常增强通常可见，这两种特征在 CT 和 MRI 上均具有特征性表现。也可以看到同侧子宫移位。
结论
讨论了可能模拟卵巢扭转的诊断陷阱以及用于鉴别它们的观察结果。
