摘要： 报告1 例从中国南方旅游归来后发生急性脑膜炎患者的临床经过。脑脊液细胞学检查发现嗜酸性粒细胞计数显著升高，符合嗜酸性粒细胞性脑膜炎，予以经验性糖皮质激素和抗寄生虫治疗后病情缓解；最终经血清学检查明确诊断为广州管圆线虫感染。对于从流行地区归来的旅游者所患的嗜酸性粒细胞性脑膜炎，应特别注意广州管圆线虫病的可能。

Abstract: A 55-year-old female traveler returning from South China with acute onset of meningitis, presenting with eosinophilic pleocytosis in the cerebrospinal fluid was reported. The etiological diagnosis of angiostrongyliasis was confirmed by detection of specific serum antibody against Angiostrongylus cantonensis. Angiostrongyliasis should be considered as a major differential diagnosis for eosinophilic meningitis in the travelers to endemic regions.
