Fat embolism in the subarachnoid space has a unique pathophysiology and clinical picture when compared to fat embolism syndrome. Lipid deposits in the subarachnoid space-most commonly the sequela of dermoid rupture in the neuraxis-can cause an inflammatory reaction leading to irritation of nearby neurovascular structures. Herein, we report the only case in the United States, to our knowledge, of a patient diagnosed with subarachnoid fat emboli secondary to sacral fracture who initially presented with a normal head CT and subsequently developed visual changes.
与脂肪栓塞综合征相比，蛛网膜下腔脂肪栓塞具有独特的病理生理学和临床表现。蛛网膜下腔的脂质沉积——最常见的是神经轴内皮样囊肿破裂的后遗症——可引起炎症反应，导致附近神经血管结构受到刺激。在此，据我们所知，我们报告了美国唯一一例因骶骨骨折继发蛛网膜下腔脂肪栓子的患者，该患者最初头部CT正常，随后出现视力变化。
