Human parvovirus B19 is a common cause of benign erythema infectiosum (fifth disease) in otherwise healthy children. Immunocompromized patients are at risk of developing chronic infections leading to chronic hyporegenerative anemia. We report the case of a nine-year-old boy who presented five days after renal transplantation with seizures and signs of encephalitis on MRI. The clinical course was characterized by anemia and seroconversion for parvovirus B19 accompanied by a high viral load (>10(9) copies per milliliter). A transfusion of red blood cells that the patient required after transplantation was found to be negative for parvovirus B19, leaving the donated organ as the most likely source of infection. Reduction of the immunosuppressive regimen led to complete recovery of the patient with a stable RBC count upon discharge. Parvovirus B19 infections should be considered in the differential diagnosis of seizures after solid organ transplantation.
