BACKGROUND AND PURPOSE: The association of syringohydromyelia with Chiari I
malformation has a wide range, between 23% and 80% of cases in the current literature. In …

Chiari malformations are a heterogeneous group of disorders with distinct clinical
anatomical features all of which involve the hindbrain. Our understanding of Chiari …

The clinical and neuroimaging characteristics of 22 consecutive patients with Chiari type I
malforma tions were evaluated to investigate the pathogenesis of syrinx formation. All …

Object Chiari malformation Type I (CM-I) with an associated spinal syrinx is a common
pediatric diagnosis. A better understanding of the relative age-related prevalence and MR …

OBJECTIVE The pathophysiology underlying tonsillar herniation and CSF obstruction in
Chiari malformation Type I (CM-I) is unclear, and the cause of CM-I–associated …

Purpose Multiple imaging parameters have been examined to estimate the presence of
syrinx and the need for surgery in Chiari I patients (CM1); however, no consistent or …

Abstract Introduction Although very uncommon, Chiari I malformation (CIM) with
syringomyelia may be associated with concomitant syringobulbia. We hypothesized that the …

Background Chiari type 1 malformation (CMI) is a disorder in which cerebellar tonsils
descend below the foramen magnum. Although syringomyelia associated with CMI thought …

Background/Aims: We performed a morphometric analysis of Chiari I malformations to look
for predictors of cervical syrinx formation. Methods: Eighteen patients with Chiari I …

The general term “Chiari malformation”(CM) refers to caudal displacement of the cerebellar
tonsils through the foramen magnum; however, this is a heterogeneous disorder with …
