We report findings of magnetic resonance imaging including susceptibility-weighted imaging (SWI) of the subacute torsion of an ovarian fibrothecoma in a patient with renal dysfunction. Although venous thrombosis within the vascular pedicle mimicked a malignant tumor, showing high signal intensity on T2-weighted images and diffusion-weighted imaging, we diagnosed ovarian torsion on SWI without the administration of contrast medium, aided by the prominent susceptibility-induced signal void caused by the thrombosis.
我们报告了一名肾功能不全患者卵巢纤维瘤亚急性扭转的磁共振成像结果，包括磁敏感加权成像（SWI）。尽管血管蒂内的静脉血栓形成在T2加权图像和扩散加权成像上表现为高信号强度，类似恶性肿瘤，但在未使用造影剂的情况下，通过SWI上血栓形成导致的明显磁敏感诱导信号缺失，我们诊断为卵巢扭转。
