Angiostrongylus cantonensis infection mimicking a spinal cord tumor

AbstractAngiostrongylus cantonensis is the most common cause of eosinophilic meningitis and meningoencephalitis. Almost all cases are self‐limiting and are diagnosed by cerebrospinal fluid eosinophilia and enzyme‐linked immunosorbent assay; pathology reports are restricted to postmortem samples from lethal cases. We report on what we believe is the first case of A. cantonensis infection diagnosed by biopsy in a living patient. The spinal cord was biopsied because of the unusual clinical presentation of a myelopathy without meningeal symptoms, together with a mass lesion that was clinically and radiologically diagnosed as a spinal cord tumor.
