title: De novo Chiari-I malformation in infants demonstrated by sequential magnetic resonance imaging scans. Report of two cases.
abstract: In this report we demonstrate the de novo development of Chiari-I malformation with hydrosyringomyelia in 2 toddlers on serial brain magnetic resonance imaging scans. We speculate that a mismatch in bony and neural development is the underlying mechanism of these de novo Chiari malformations.
