Arnold-Chiari malformation

A congenital compression deformity of the lower brain, which is characterised by herniation of the cerebellar tonsils and distal medulla oblongata through the foramen magnum into the spinal canal. The Arnold-Chiari malformation is accompanied by compression of the 4th ventricle and firm adhesions at the cisterna magna.
