Insidious hydrocephalus in the preterm newborn following discharge from the nursery.
Posthemorrhagic ventriculomegaly may be due to perinatal brain damage and consequent cerebral atrophy, or represent progressive hydrocephalus due to impairment of CSF flow and reabsorption. 'Arrested' hydrocephalus occurs when the CSF pathways are adequate and, hence, intracranial hypertension no longer exists. The differential diagnosis is often difficult and insidious progressive hydrocephalus should always be a concern in the high-risk preterm newborn. We report 10 preterm infants who were discharged with the diagnosis of arrested hydrocephalus (7) or cerebral atrophy (3), and who later developed progressive severe hydrocephalus 1.5-15 months after the discharge. Five had been treated with intermittent lumbar punctures, while 4 had not received any treatment prior to nursery discharge. One infant died prior to the shunt procedure. Progressive insidious hydrocephalus should be suspected in preterm infants with intracranial hemorrhage following discharge from the nursery.
