title: Sudden infant apnea and insidious hydrocephalus.
abstract: Hydrocephalus secondary to intracranial-intraventricular hemorrhage is a common complication in the clinical course of the high-risk preterm newborn. Hydrocephalus in this population may be insidious without obvious intracranial hypertension. Apnea and respiratory arrest continue to cause concern following nursery discharge of the high-risk preterm newborn. We report a child who presented to the neonatology service with episodes compatible with serious sudden cardiorespiratory arrest. Insidious "non-hypertensive" hydrocephalus was documented as being responsible for these episodes, which resolved with treatment of the hydrocephalus. The perinatal neurosurgical consultant should be aware of this syndrome and instruct the parents and the pediatricians of these infants, who at the time of discharge are asymptomatic but have ventricular enlargement on neuro-imaging studies. The information presented here is of current importance, since most neonatologists are unaware of the syndrome of insidious hydrocephalus.
