Subarachnoid fat is an uncommon finding that has several etiologies. It is important to determine the etiology in order to plan appropriate treatment. We present a case report of an 80-year-old female brought to the emergency department after a fall with complaints of headache and pain in the sacral region. Computed tomography and magnetic resonance images of the head demonstrated fat in the subarachnoid space. Computed tomography and magnetic resonance images of the sacrum demonstrated a Tarlov cyst with a sacral fracture extending into the cyst, likely representing the origin of the fat in the subarachnoid space. This case demonstrates a rare etiology of fat in the subarachnoid space.
蛛网膜下腔脂肪是一种少见的发现，有多种病因。确定病因对于制定恰当的治疗方案很重要。我们报告一例80岁女性病例，该患者因跌倒后出现头痛和骶部疼痛被送至急诊科。头部计算机断层扫描（CT）和磁共振成像（MRI）显示蛛网膜下腔内有脂肪。骶骨的CT和MRI显示一个Tarlov囊肿，伴有延伸至囊肿内的骶骨骨折，这可能是蛛网膜下腔脂肪的来源。该病例展示了蛛网膜下腔脂肪一种罕见的病因。
