Abstract:
A case of a child with subacute neurologic features and imaging findings consistent with a brainstem encephalitis that was discovered to be related to a primary central nervous system infection caused by Epstein-Barr virus is presented. A brainstem tumor was initially suspected, but a correct diagnosis was formulated on the basis of the favorable clinical course and the detection of positive Epstein-Barr virus serology. In contrast to a prompt recovery of neurologic signs the neuroimaging alterations persisted for a longer time. The present report emphasizes the possible role of Epstein-Barr virus in the pathogenesis of infectious neurologic disorders in childhood, underlining the unusual presentation of a brainstem encephalitis, and considers the discrepancy between the course of neurologic features and the evolution of imaging alterations.
