Idiopathic external hydrocephalus in infants typically presents with macrocephaly and developmental delays but has a benign course. Clinical and imaging improvements are observed by age 4.

Area of Science:

  • Pediatric Neurology
  • Neuroimaging
  • Developmental Pediatrics

Background:

  • Idiopathic external hydrocephalus (IEH) is a rare condition.
  • Characterized by enlarged subarachnoid spaces without significant ventricular dilation.
  • Often presents in infancy with macrocephaly and hypotonia.

Purpose of the Study:

  • To describe the clinical presentation, neuroimaging findings, and natural history of idiopathic external hydrocephalus in male infants.
  • To evaluate the developmental outcomes and long-term prognosis of this condition.

Main Methods:

  • Case series of 5 male infants diagnosed with idiopathic external hydrocephalus within their first year of life.
  • Clinical assessments including developmental milestones and physical examinations.

  • Computed tomography (CT) scans for neuroimaging evaluation.

    • Main Results:

    • All 5 infants presented with macrocephaly, hypotonia, and mild to moderate delays in language and gross motor development; cognition was normal.
    • CT scans revealed enlarged subarachnoid spaces with normal or mildly dilated lateral ventricles.
    • A benign clinical course was observed, with improvement in developmental delays by age 4 and normalization of CT findings.

    Conclusions:

    • Idiopathic external hydrocephalus in male infants is a benign condition with a favorable prognosis.
    • Developmental delays associated with IEH typically resolve by early childhood.
    • Neuroimaging and clinical monitoring are essential for diagnosis and management.
