Chiari malformations (CM) are caused by problems in the structure of the brain and skull. (nih.gov)
Chiari malformation occurs when your skull is smaller than normal, or is misshapen, and presses on your brain, pushing it down. (healthonecares.com)
BACKGROUND: Syringomyelia is defined as dilation of the spinal cord's central canal and is often precipitated by skull base herniation disorders. (bepress.com)
While still mostly associated with cerebellar herniation, we continue to discover new structural skull and vertebral malformations that are involved which complicates our understanding of it. (hallmarq.net)
There is recent evidence that CM involves a malformation of the entire skull, with the intracranial volume being too small to accommodate the intracranial contents. (vin.com)

Craniometric studies document different subtypes of craniocervical junction malformations (CCJM). (surgicalneurologyint.com)
1 ] Here, we analyzed the different frequencies of SS, between these three CCJM subtypes with/without syringomyelia. (surgicalneurologyint.com)

Traditionally, Chiari-like malformation was described as a cerebellar herniation. (hallmarq.net)
