An infectious illness, attributed to atypically structured cytopathic "stealth" viruses, occurred in 1996 in the Mohave Valley region of the United States. A stealth virus-infected child from this region has developed a severe noninflammatory, vacuolating (spongiform) encephalopathy. The illness initially presented as a behavioral problem without overt neurological signs. Extensive investigations, including repeated magnetic resonance imaging, two brain biopsies, and stealth virus cultures, have helped define the disease process occurring in this child. Significant clinical benefit with apparent retardation of disease progression occurred during a 6-week course of ganciclovir therapy. The potential contributing role of stealth virus infections in children presenting with behavioral problems needs to be addressed. (C) 1999 Academic Press.
