Torsion of the adnexa can be the cause of abdominal pain. An immediate diagnosis is very important because early surgical intervention is the only way to save the ovary from necrosis. Torsion of a normal adnexa is rare, but occurs more frequently than is generally appreciated. If US findings are equivocal, MRI can provide additional information. In our case the MRI findings leading to the diagnosis of ovarian torsion were: (a) A medial ovarian mass existed with dislocation of the uterus to the affected side with hyperintense, cystic lesions on T2-weighted images at the periphery of the ovary. (b) Beaked protrusion of the mass continuing in a band-like structure connecting it with the uterus obviously represented the Fallopian tube. (c) Low and inhomogeneous signal intensity of the stroma on T1- and T2-weighted images and lack of gadolinium uptake were indicative of infarction.
附件扭转可能是腹痛的原因。立即诊断非常重要，因为早期手术干预是使卵巢免于坏死的唯一方法。正常附件扭转很少见，但实际发生率比普遍认为的要高。如果超声检查结果不明确，磁共振成像（MRI）可以提供更多信息。在我们的病例中，导致卵巢扭转诊断的MRI表现为：（a）卵巢内侧有肿块，子宫向患侧移位，卵巢周边在T2加权图像上有高信号囊性病变。（b）肿块呈鸟嘴状突出，并延续为连接它与子宫的带状结构，显然代表输卵管。（c）在T1加权和T2加权图像上，间质信号强度低且不均匀，且无钆摄取，提示梗死。
