Primary infection with EBV in childhhod is generally silent but can often cause overt diseases such as infectious mononucleosis and lymphoproliferative disorders. In developed countries primary infection of EBV is usually delayed untill adolescence.Neurologic complications are relatively rare in children with EBV infections, occuring aproximately in 8% of those infected.The incidence of facial nerve palsy associated with EBV infection is unknown,although in one study  concerning the complications in children with EBV infection, the incidence was found  0.9%. We present an 11 month old infant with a 4 days history of fever, 2 days history of facial weakness and mild cough.Physical examination revealed small cervical lymphnodes, (L) otitis media and (L) facial nerve palsy.Neurological examination was otherwise normal.No generalised lymphadenopathy was found.Liver was palpable 2 cm below the costal margin and there was no splenomegaly. His previous medical history was unremarcable.There was no evidence of immunodeficiency and he has not received any cytotoxic or steroid  medication . Initial laboratoty tests showed marked leucocytosis with atypical lymphocytes.WBC: 82100/¦Ìl  with lymphocytes: 70.9%. The hemoglobin was 11.5 g/dl and platelets 284000/¦Ìl. CRP and ESR were not raised. Hepatic transaminases were slightly elevated: SGOT: 76U/L,SGPT: 58U/L. Primary EBV infection was established by serologic examination for  specific EBVantibodies: VCA-IgM(+), VCA-IgG:1/320, EA<1/20,EBNA<1/20. Bone marrow aspirates showed increased number of polyclonal B lymphocytes and no malignant infiltration.Also no monoclonality of the B lymphocyte was detected either by flowcytometry immunophenotype or immunoglobulin gene rearangement. Chromosomal analysis was normal. Serologic examination for other viral infections such as HSV,CMV, HIVand Hepatitis A,B,C were negative.Ther was no evidence of Lyme disease. Middle ear fluid was obtained by tympanocentesis was sterile on culture. Facial nerve palsy gradually resolved with no treatment and WBC returned to normal after 3 weeks time.During the following 6 months the patient had 2 episodes with similar clinical and hematological findings.

Conclusion: This is a rare presentation of recurrent EBV infection with extreme leucocytosis and facial nerve palsy.
