Postoperative visual loss is rare and most often due to posterior ischemic optic neuropathy. We describe optic nerve MR imaging of a 37-year-old man with postoperative visual loss due to posterior ischemic optic neuropathy after complicated aortic aneurysm surgery. MR demonstrated restricted diffusion and focal enhancement of both optic nerves. Combined restricted diffusion and focal enhancement is a unique MR imaging feature with postoperative vision loss.
术后视力丧失很少见，且大多是由后部缺血性视神经病变所致。我们描述了一名37岁男性在复杂主动脉瘤手术后因后部缺血性视神经病变导致术后视力丧失的视神经磁共振成像（MR）表现。MR显示双侧视神经扩散受限和局灶性强化。扩散受限和局灶性强化并存是术后视力丧失独特的MR成像特征。
