Dandy-Walker malformation (DWM) is a complex brain defect. Recent MRI findings show that the cerebellum

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Medical Genetics

Context:

  • Dandy-Walker malformation (DWM) is a rare congenital brain anomaly.
  • Characterized by vermian hypoplasia, cystic fourth ventricle, and posterior fossa enlargement.
  • Frequently associated with genetic, neurological, and systemic malformations, complicating diagnosis and prognosis.

Purpose:

  • To review current knowledge on Dandy-Walker malformation (DWM).
  • To introduce recent advancements in understanding DWM prognosis.
  • To clarify diagnostic criteria and natural history.

Summary:

  • DWM definition has varied due to rarity and diagnostic challenges.
  • Hydrocephalus is less common in prenatal series than previously thought.
