Unlike types I-III, Chiari malformation type IV is not associated with herniation of the brain through the foramen magnum. A measurement is then drawn perpendicular to this plan between it and the tip of the cerebellar tonsils, either in the midsagittal image or an adjacent parasagittal image, wherever the tonsils are most low lying 10,11. This condition affects individuals of every race and ethnicity. Removal of part of the bony covering of the spinal canal (laminectomy) in order to provide more room for cerebrospinal fluid circulation and to remove scar tissue.
