Neurosonographic recognition of subependymal cysts in high-risk neonates.
Serial neurosonography was performed in 210 high-risk, preterm neonates. Eleven (5.8%) demonstrated small cystic formations in the subependymal lining of the lateral ventricles. These subependymal cysts were unilateral and were detected at the exact site of a previous subependymal hemorrhage in two cases. These 11 infants were not significantly different in maturity, size, or clinical parameters from our main high-risk newborn population. Ten survivors had marked motor retardation at follow-up ages of 9-13 months, and one died from neonatal sepsis.
