Discussion :
Congenital hydrocephalus. Aqueductal stenosis (narrowing) is the most frequent cause. Blockage of fourth ventricle outlet (Dandy Walker Syndrome) or Chiari malformations (in association with Spina Bifida) are other common causes of congenital hydrocephalus. Ultrasonography (USG), computerized Tomography (CT scan) or magnetic resonance Imaging (MRI) will confirm the diagnosis; show the degree of ventricular enlargement, the site of the blockage and offending cause(s). |
