저자들은 임상적 소견과 검사실 소견에서 전염성 단핵구증으로 확진한 환아에게서 폐렴과 흉막 삼출액이 동반된 드문 1례를 경험하였다. 이에 문헌고찰과 함께 보고하는 바이다.

Infectious mononucleosis(IM) is a clinical syndrome characterized by fever, exudative tonsillitis, gerneralized lymphadenopathy(90% of cases), splenomegaly(50% of cases), and hepatomegaly(10% of cases). It is mainly caused by Epstein-Barr virus(EBV) and usually recovered completely in the majority of cases. The complications of IM are splenic rupture, pancreatitis, hematologic problems such as hemolytic anemia, aplastic anemia, and thrombocytopenia, neurologic problems such as meningitis, encephalitis, and Guillian-Barr$\acute{e}$ syndrome, myocarditis, parotitis, orchitis, and interstitial pneumonitis, etc. Pulmonary involvement with EBV infection is rare condition reported frequency of 3% to 5%, in addition pleural effusion has been very rarely reported, especially in the pediatric population. We herein report a case of IM with pleural effusion in 3 years old boy with fever, cervical lymphnodes enlargement, and hepato-splenomegaly. And the pleural effusion is spontaneously resolved for a hospitalization period. A brief review of literature is included.
