Objective: To determine differential patterns of brain atrophy in pediatric AIDS encephalopathy. Design: We measured the bicaudate, bifrontal, and ventricle-brain ratio in brain magnetic resonance imaging scans of 42 control children, nine children with progressive AIDS encephalopathy, 25 AIDS children without progressive encephalopathy, and 23 children with cerebral atrophy of other causes. Results: When compared with controls, encephalopathy patients showed significantly increased bicaudate and ventricle-brain ratios, but no significant increase in bifrontal ratio, whereas children with brain atrophy from causes other than AIDS showed increases in all three ratios. Conclusion: Children with AIDS encephalopathy demonstrate a specific pattern of brain atrophy distinct from other etiologies: a central atrophy, primarily affecting the subcortical white matter or the basal ganglia regions.
