Magnetic resonance imaging (MRI) brain: additional features in Chiari type II

  • Abnormal hippocampi 
  • Low anterior commissure in the lamina terminalis
  • Corpus callosum ridge: an abnormal bundle of white matter on the dorsal callosal surface
  • Deficient posterior hemispheric white matter
  • Stenogyria: multiple small compacted gyri separated by shallow sulci 
  • Gray matter heterotopias 
  • Thin and dysplastic posterior limbic cortex 

Magnetic resonance imaging (MRI) whole spine

Other investigations

Indications for surgery

Foramen magnum decompression (FMD): associated procedures
