摘要

廣東住血線蟲最先是在中國大陸廣東地區老鼠的肺中發現，在東南亞及太平洋四周的島嶼是造成嗜伊紅性腦膜炎與腦膜腦炎常見的病因．本篇報告一嗜伊紅性腦膜炎的病例．病患於住院前四星期有生吃蝸牛的病史，頭部電腦斷層檢查正常，但是磁振造影以質子，T2以及靜脈注射Gadolinium-DTPA T1為主的影像可見散在性點狀或管狀等高訊號強度病灶，以我們的經驗來說，此種現像不是一般所見的細菌性以及病毒性腦膜炎或腦膜腦炎，最後血清學ELISA檢查證實為此病症。

Angiostrongylus cantonensis, first reported in rat's lung in Canton, is a common etiology of eosinophilic meningitis or eosinophilic meningoencephalitis in South East Asia and the Pacific islands. We reported a case of eosinophilic meningitis having history of eating raw snail 4 weeks prior to admission. Brain CT appeared normal, while MRI showed multiple small dotted and tubular- like high signal intensity lesions disseminated in the deep and superficial cerebrum and cerebellum in PDI, T2WI and GadoliniumDTPA T1WI. The serology of ELISA proved it as Angiostrongylus cantonensis. To our experience, this picture was unusual in bacterial and viral meningitis or meningoencephalitis, and may be suggestive of eosinophilic meningitis by Angiostrongylus cantonensis.
