Three patients with eosinophilic meningitis (EoM) were investigated in two hospitals in Porto Alegre, Southern Brazil. These patients had a common exposure after the ingestion of raw mollusks in a religious ritual. Two of them had an uncommon presentation with intense lower distal extremities pain and small fiber neuropathy as defined by an electroneuromyography (ENMG) study. All three patients were positive for Angiostrongylus cantonensis serology and recovered after antihelminthic and anti-inflammatory treatment. Increased awareness of A. cantonensis infection is important to avoid new infections and to improved recognition and handling of cerebral angiostrongyliasis.

巴西南部阿雷格里港的两家医院对三名嗜酸性粒细胞性脑膜炎（EoM）患者进行了调查。这些患者在宗教仪式中摄入原始软体动物后，经常接触。根据电镜检查（ENMG）的研究，其中两个患者表现出罕见的下肢剧烈疼痛和小纤维神经病变。所有三例患者的广州血管圆线虫血清均为阳性，经抗蠕虫和抗炎治疗后均恢复。提高对广州曲霉感染的认识对于避免新发感染以及改善对脑血管平滑肌病的认识和处理很重要。
