title: Benign subdural collections of infancy.
abstract: Four asymptomatic infants with macrocrania, abnormal transillumination, and characteristic computed tomography scans are described. All had bilateral subdural collections, normal brain size, modest ventricular enlargement, and prominent cerebral sulci and interhemispheric fissures. Although these latter findings are often interpreted as atrophy, these infants had normal development and rapidly growing heads. No treatment beyond diagnostic subdural punctures was performed. After up to 13 months of follow-up, the size of the subdural collections was either stable or decreasing in all four infants.
