The high mortality rate is associated with deficient immune system reconstitution after hematopoietic stem cell transplant (HSCT) and poor bioavailability of antiviral drugs in cerebrospinal fluid (CSF). CMV\u2010related central nervous system (CNS) infection may occur with aspecific symptoms, without evidence of either blood viral load or magnetic resonance imaging (MRI) signs of encephalitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Here, we describe a 10\u2010year\u2010old girl who underwent an allogeneic HSCT and subsequently developed CMV encephalitis. Because of the absence of CMV antigen in the blood, the diagnosis of encephalitis was proposed only after a delay, following the onset of immune reconstitution inflammatory syndrome (IRIS). Two months of combined dual antiviral therapy with ganciclovir and foscarnet proved ineffective against CMV and caused significant bone marrow and renal toxicity. To avoid further toxicity, the girl was given daily treatment with CMV\u2010hyperimmune globulins alone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After three weeks, the CSF viral load dropped significantly and was undetectable within three more weeks.

succeeded in achieving CMV CSF clearance with high dose of CMV\u2010hyperimmune globulin, given alone, because of the ability of immunoglobulins to penetrate the blood\u2013brain barrier
