A 10-year-old male with a brain abscess developed pancytopenia, liver dysfunction, disseminated intravascular coagulation (DIC) and decrease of immunoglobulin A (IgA) level during postoperative antibiotic and anticonvulsant therapy. A bone marrow examination revealed hemophagocytosis. Real-time PCR revealed parvovirus B19 infection. The hemophagocytic syndrome resolved without specific treatment. To our knowledge, this is the first report of a spontaneous resolution of parvovirus B19-associated hemophagocytic syndrome and DIC.
