OBJECT In 1998 the authors identified 5 patients with syringomyelia and no evidence of Chiari malformation Type I (CM-I). Magnetic resonance imaging of the entire neuraxis ruled out other causes of a syrinx. Ultimately, abnormal CSF flow at the foramen magnum was the suspected cause. The label "Chiari 0" was used to categorize these unique cases with no tonsillar ectopia. All of the patients underwent posterior fossa decompression and duraplasty identical to the technique used to treat patients…

Management of isolated syringomyelia in the paediatric population – a review of imaging and follow-up in a single centre
In a small minority who have progressive back pain, it is found that lumbar puncture may be helpful in reducing symptoms and Idiopathic syrinx is a benign pathology, which can be managed expectantly.
A novel classification and its clinical significance in Chiari I malformation with syringomyelia based on high-resolution MRI
Postoperative re-examination showed that the size of the syringomyelia was reduced or completely resolved in patients of Type A, 100% (2/2); Type B, 81% (9/11); Type C, 84% (81/97); and Type D, 20% (1/5); according to the new classification based on HRMRI, FMMD is the key to surgical treatment, especially for Type A and Type B patients.
Idiopathic syringomyelia: retrospective case series, comprehensive review, and update on management.
Review of the literature suggests that an etiology-driven approach is essential in the diagnosis and management of syringomyelia, although conservative management suffices for most cases.
Adult Chiari I malformation - Clinical presentation and surgical outcomes
This thesis focuses on the following three atypical presentations of Chiari I malformations: swallowing difficulty, neuropsychological (NP) dysfunction and acute deterioration, and the impact of CMI on patient quality of life (QOL).
Surgical outcome of Chiari I malformation in children: clinico-radiological factors and technical aspects
In most pediatric Chiari I patients with hydrocephalus, a shunting operation was sufficient and foramen magnum decompression (FMD) showed high efficacy in treating patients without hydrocephalu, and FMD was less effective for scoliosis.
The Chiari I malformation.
The authors will discuss the evolution in understanding of the Chiari malformation and distinguish between symptomatic CIM and asymptomatic tonsillar ectopia, based on imaging and presenting symptomatology, and discuss techniques for surgical intervention, expected outcomes, and complications after surgery.
Chiari Type 1 Deformity in Children: Pathogenetic, Clinical, Neuroimaging, and Management Aspects.
"Chiari type 1 deformity" is the correct term to characterize primary tonsillar herniation and future studies are needed to provide selection criteria with a higher sensitivity and specificity.


Analysis of the Posterior Fossa in Children with the Chiari 0 Malformation
The findings of this study suggest that the contents of the posterior fossa are indeed compromised and/or distorted in patients with syringohydromyelia but no tonsillar ectopia.
Syringomyelia without hindbrain herniation: tight cisterna magna. Report of four cases and a review of the literature.
Syringomyelia associated with tight cisterna magna should not be classified as idiopathic syringomy Amelia; rather, it belongs to the category of organic syringomers such as Chiari malformation, and may respond to craniocervical decompression.
The resolution of syringohydromyelia without hindbrain herniation after posterior fossa decompression.
The authors hypothesize the rare occurrence of syringohydromyelia resulting from a Chiari-like pathophysiological condition but lacking a hindbrain hernia, and suggest patients with this condition may benefit from craniocervical decompression.
Clinical and neuroimaging features of “idiopathic” syringomyelia
In some adult patients with cervical syringomyelia, MRI studies do not identify primary disease within the foramen magnum or spinal canal, and clinical features and posterior fossa measurements from 17 patients, 17 patients with Chiari I-type syringitis, and 32 control subjects were compared, suggesting that they develop by the same mechanism.
Acute Hydrocephalus following a Chiari I Decompression
Three patients who developed infratentorial supracerebellar hygromas causing acute hydrocephalus after posterior cranial fossa decompression are presented.
