C57BL/6 mice develop T-cell-mediated experimental autoimmune encephalomyelitis (EAE) after immunization with the neuroantigen myelin oligodendrocyte glycoprotein. (MOG). We immunized CD28-deficient C57BL/6 mice to determine the role of T cell costimulation in the immune response to MOG. CD28-/- mice developed experimental autoimmune meningitis (EAM). EAM is a fatal, acute disease characterized by simultaneous weakness in all limbs, photophobia, irritability, and spatial disorientation. Histologically, EAM consisted of an infiltrate of myeloid, monocytic, and lymphocytic leukocytes within the leptomeninges. In contrast, the brain parenchyma was unaffected. EAM was mediated by CD4+ T cells since CD4 depletion prevented the disease. Upon rechallenge, mice in which EAM was prevented by CD4+ cell depletion developed EAE not EAM. Therefore, the presence or absence of CD28 determines the initial phenotype of the immune response to MOG. EAM, which develops in the absence of CD28, is a unique experimental model for immune-mediated aseptic meningitis.

A case of acute disseminated encephalomyelitis in 13-year-old boy associated with enterovirus is described. The patient had symptoms of severe headache and photophobia for 2 days. Diagnosis was made on the basis of diffuse high intensity white matter lesions in the left frontoparietal region seen on magnetic resonance imaging, and positive enterovirus polymerase chain reaction in cerebrospinal fluid. His symptoms improved substantially without specific therapy, and he recovered without neurologic sequelae.
