Epstein-Barr virus (EBV) infection has been associated with infectious mono
nucleosis, EBV-associated hemophagocytic syndrome (EBV-AHS), chronic active
EBV infection (CAEBV), lymphomas, inflammatory pseudotumor, lymphomatoid g
ranulomatosis, and nasopharyngeal carcinoma. EBV-AHS and CAEBV are more let
hal than infectious mononucleosis with imaging findings of gallbladder wall
thickening, pleural effusion, cardiomegaly, and hepatomegaly. EBV infectio
n is also associated with benign and malignant tumors. (C) 2001 Elsevier Sc
