くも膜下腔の脂肪塞栓症は、脂肪塞栓症症候群と比較すると、ユニークな病態生理と臨床像を持っています。くも膜下腔内の脂質沈着-最も一般的には神経軸のdermoid破裂の後遺症-は、近くの神経血管構造の刺激につながる炎症反応を引き起こす可能性があります。ここでは、我々の知る限りでは米国で唯一の症例である仙骨骨骨折に続発するくも膜下脂肪塞栓症と診断された患者について報告する。

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.
