Posterior cranial fossa morphometry in symptomatic adult Chiari I malformation patients: Comparative clinical and anatomical study
Morphometric Analysis of the Posterior Cranial Fossa in Chiari Type I Malformation in Adults.
TLDR
It is illustrated that the bony components of the posterior cranial fossa is underdeveloped in CMI, which supports the current literature stating that CMI is the result of underdeveloped occipital somites and the paraxial mesoderm.
Morphometric analysis of posterior fossa and craniovertebral junction in subtypes of Chiari malformation
Comparison of posterior fossa volumes and clinical outcomes after decompression of Chiari malformation Type I.
TLDR
A greater increase in the postoperative PCF volume, and specifically an increase inThe cisterna magna volume, was associated with a greater likelihood of clinical improvements in headache and tonsillar descent in patients with CM-I.
Chiari type I malformation with high foramen magnum anomaly.
A 14-year-old male with a neck pain and hypoesthesia in the upper extremities was diagnosed with Chiari type I malformation (CMI) and syringomyelia. The posterior part of the occipital bone was…
Computed tomographic study of posterior cranial fossa, foramen magnum, and its surgical implications in Chiari malformations
TLDR
The normal dimensions of the posterior fossa and FM were less in females than males and were useful to radiologists and neurosurgeons to better their diagnostic inferences, as well as to determine the proper treatment options in Chiari malformation type I (CMI) and other posterior Fossa anomalies.
Posterior odontoid process angulation in pediatric Chiari I malformation: an MRI morphometric external validation study.
TLDR
The authors found that the population at their center was characterized by posterior angulation of the odontoid process in 81% of cases, similar to findings by Tubbs et al. (84%).
The Intracranial and Posterior Cranial Fossa Volumes and Volume Fractions in Children: A Stereological Study
TLDR
It is revealed that point counting method can produce accurate volume estimations and is effective in determining volum e estimation of intracranial cavity and posterior cranial fossa volume.

Correlation of Functional Outcome and Natural History With Clinicoradiological Factors in Surgically Managed Pediatric Chiari I Malformation
TLDR
More than half the pediatric patients with Chiari I malformation improve after surgery, and the age at presentation, duration and type of symptoms, cranial and foramen magnum morphometry, and syrinx-related changes have no bearing on outcome at short-term follow-up.

Posterior fossa volume in children with Chiari malformation Type I.
TLDR
Whether the volume of the posterior fossa in children suffering from Chiari malformation Type I (CM-I) is smaller than normal, as has been suggested previously, is investigated and it is indicated that the two subgroups may represent different phenotypic expression or even a different pathogenesis.
Posterior fossa dimension and volume estimates in pediatric patients with Chiari I malformations
TLDR
Mean PFV values were found to be smaller in pediatric CMI patients than control patients; this complements earlier studies in adults and supports the present theory concerning the pathophysiological mechanism of CMI.
Pathogenesis of Chiari malformation : a morphometric study of the posterior cranial fossa
TLDR
The results suggest that in adult-type Chiari malformation an underdeveloped occipital bone, possibly due to underdevelopment of the occipITAL somite originating from the paraxial mesoderm, induces overcrowding in the posterior cranial fossa, which contains the normally developed hindbrain.
Skull base growth in children with Chiari malformation Type I.
TLDR
Children with CM-I have abnormal geometrical measurements of their entire skull base, not only the posterior fossa, irrespective of presence of syringomyelia, which may indicate a mesodermal defect as a possible cause of the malformation.
Dimensions of the posterior fossa in patients symptomatic for Chiari I malformation but without cerebellar tonsillar descent
TLDR
Preliminary morphologic data suggests that a subgroup of patients exists with tonsillar descent less than 3 mm below the foramen magnum but with congenitally hypoplastic posterior fossa causing symptomatology consistent with CMI.
Chiari I malformation redefined: clinical and radiographic findings for 364 symptomatic patients.
TLDR
These data support accumulating evidence that CMI is a disorder of the para-axial mesoderm that is characterized by underdevelopment of the posterior cranial fossa and overcrowding of the normally developed hindbrain.
Chiari I anatomy after ventriculoperitoneal shunting: posterior fossa volumetric evaluation with MRI
IntroductionCephalocranial disproportion was said to be responsible for Chiari I malformation after ventriculoperitoneal shunt. We aimed to evaluate if the volumetric characteristics of Chiari I…
Sagittal Profiles of the Spine in Scoliosis Associated With an Arnold-Chiari Malformation With Or Without Syringomyelia
TLDR
A retrospective review of scoliosis secondary to ACS from three centers was undertaken and a positive correlation was noted between cervical lordosis (CL) and thoracic kyphosis (TK) and a clinician should strongly suspect the presence of an Arnold-Chiari I malformation with or without syringomyelia.
Scoliotic Curve Patterns in Patients With Chiari I Malformation and/or Syringomyelia
TLDR
Although the decision to obtain magnetic resonance imaging in a patient with scoliosis should be based on both clinical and radiographic criteria, it is suggested that a heightened index of suspicion is warranted with certain curve patterns, and with a high or low apex and/or end vertebra, especially in males and patients with a normal to hyperkyphotic thoracic spine.
The role of cine flow MRI in children with Chiari I malformation
TLDR
All patients with Chiari I malformation and an associated cervical syrinx had absent cine flow at the craniovertebral junction, and this finding was statistically significant.
