Dandy-Walker Malformation (DWM) – Tetra-Ventriculomegaly

In this lecture you will learn how to image and diagnose Dandy-Walker malformation (DWM) using 2D and 3D/4D ultrasonography.

Dandy-Walker Malformation (DWM) is characterized by the association of:

  1. Hydrocephalus of variable degree of the all ventricular cavities of the brain (tetra-ventriculomegaly).
  2. Cyst in the posterior cranial fossa.
  3. Cerebellar inferior vermian defect through which,
  4. The cyst communicates with the fourth ventricle.
