Tubbs, R.S., 2015a. Definitions and Anatomic Considerations in Chiari I Malformation and Associated Syringomyelia. Neurosurg. Clin. N. Am. 26, 487–493. doi:10.1016/j.nec.2015.06.007

ABSTRACT

Current understanding of the hindbrain hernias known as Chiari I malformations is based on more than 100 years of pathologic and clinical experience. Over time, the definition of this finding has been analyzed and altered. The term Chiari I malformation is currently used to describe tonsillar ectopia in a wide range of patients with varying embryonic derailments. This article discusses this malformation, its various definitions, and varied anatomic traits. In addition, the morphology of the commonly associated syringomyelia is reviewed.
