Transient isolated lesion of the splenium associated with clinically mild influenza encephalitis.
Transient isolated lesions of the splenium with restricted diffusion are rare in the pediatric population. We report two such cases with influenza-associated encephalitis/encephalopathy (IAEE). These reversible isolated central splenial lesions are not specific for IAEE, but the notable feature associated with this specific presentation is a comparatively milder form of encephalitis that resolves clinically and radiologically within a short time.
