Aseptic meningitis induced by intravenous immunoglobulins in a child with acute Epstein-Barr virus infection and thrombocytopenia.

Drug-induced aseptic meningitis (DIAM) represents a diagnostic challenge since clinical and cerebrospinal fluid (CSF) findings may be indistinguishable from a bacterial meningitis. Intravenous immunoglobulin (IVIg) are commonly used in a variety of diseases, including inflammatory and autoimmune disorders. Although usually well-tolerated, various adverse effects have been reported. DIAM is a serious neurological side effect of IVIg therapy: albeit rare (0.067% of all IVIg infusions), the condition represents an important diagnostic challenge and should be considered by physicians. Here we report a case of an aseptic meningitis induced by IVIg therapy in a child with acute Epstein-Barr virus (EBV) infection and thrombocytopenia.
