Infections are an uncommon but very important etiology of myelitis as a correct diagnosis would allow for timely treatment and recovery. The term "myelitis" is generally used to describe an inflammatory pathologic process affecting the spinal cord and causing an interruption of the ascending and descending pathways, and, therefore, partial or complete loss of function. The onset may be acute or subacute, and the etiology may be cumbersome to determine. This article will review the most recently published literature regarding the infectious agents causing myelitis with an emphasis on diagnosis and treatment.

Cerebral schistosomiasis and spinal schistosomiasis are severe underrecognized complications of Schistosoma sp. infection, and can occur at any time during the parasitic infection. Neuroschistosomiasis has been increasingly reported not only in endemic areas but also in Western countries owing to immigration and international travel. Immunogenic interaction between schistosome egg deposition and the delayed hypersensitivity reaction of the host are the main neuropathogenic mechanisms involved. ⋯ Headache and seizures are common in cerebral schistosomiasis, and intracranial hypertension and hydrocephalus may occur in tumour-like and cerebellar schistosomiasis. Spinal schistosomiasis may manifest itself as acute myelitis and/or myeloradiculopathy. Recognition of neuroschistosomiasis is important so that early treatment with praziquantel and steroids can be started in an attempt to prevent severe disability.
