Evolutionary hypothesis for Chiari type I malformation [PDF]

open access: yes, 2015
Chiari I malformation (CM-I) is classically defined as a cerebellar tonsillar herniation (>= 5 mm) through the foramen magnum. A decreased posterior fossa volume, mainly due to basioccipital hypoplasia and sometimes platybasia, leads to posterior fossa ...
