Headache is a common presenting complaint in the emergency department (ED) that sometimes requires a diagnostic workup including a lumbar puncture (LP). An LP is often used to evaluate patients in the ED for an acute neurologic process. Xanthochromia seen on cerebrospinal fluid from an LP is often considered to be highly suggestive of a subarachnoid hemorrhage. We describe 2 cases where gross xanthochromia was noted during LP but the patients did not have an acute subarachnoid hemorrhage.
头痛是急诊科常见的就诊主诉，有时需要进行包括腰椎穿刺（LP）在内的诊断性检查。LP常用于评估急诊科患有急性神经疾病的患者。LP获取的脑脊液中出现黄变通常被认为高度提示蛛网膜下腔出血。我们描述了2例在LP过程中发现明显黄变但患者并无急性蛛网膜下腔出血的病例。
