PRIMARY OBJECTIVE Chiari malformation is defined as herniation of the cerebellar tonsils through the foramen magnum, also known as cerebellar tonsillar ectopia (CTE. [...] Key MethodSTUDY DESIGN Case-control. METHODS AND PROCEDURES Cervical MRI scans for 1200 neck pain patients were reviewed; 600 trauma (cases) and 600 non-trauma (controls). Half of the groups were scanned in a recumbent position and half were scanned in an upright position.Expand
Is there a relationship between the extent of tonsillar ectopia and the severity of the clinical Chiari syndrome?
TLDR
The severity of the symptoms associated with the Chiari malformation does not correlate directly with the extent of tonsillar ectopia, and the extent should be re-evaluated as the threshold for diagnosis of Chiari 1 malformation.

TLDR
Neither the severity of subjective symptoms and objective neurological finding nor the intraoperative findings other than tonsillar pallor correlated with the extent oftonsillar ectopy in patients with Chiari malformation type 1 (CMI).
Epidemiology of Symptomatic Chiari Malformation in Tatarstan: Regional and Ethnic Differences in Prevalence.
TLDR
Assessments of the health impact of CM1-type symptoms on a patient population should include the bCM1 patient group, a regional disease cluster of patients with Chiari malformation found in Baltasy district of RT and needs further study.
Tonsillar herniation spectrum: more than just Chiari I. Update and controversies on classification and management
TLDR
The hypothesized mechanisms of development of tonsillar herniation are reviewed and strategies of management are discussed, with particular attention to surgical options adapted to the underlying etiology.
Signs of Intracranial Hypertension, Hypermobility, and Craniocervical Obstructions in Patients With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
TLDR
A large overrepresentation of hypermobility, signs of intracranial hypertension (IH), and craniocervical obstructions may be overrepresented in patients with ME/CFS and thereby explain many of the symptoms.
The Craniocervical Junction: Observations regarding the Relationship between Misalignment, Obstruction of Cerebrospinal Fluid Flow, Cerebellar Tonsillar Ectopia, and Image-Guided Correction
TLDR
Image-Guided Atlas TreatmentTM (IGATTM) has been shown to be a method of gentle correction of misalignment of C₀-C1, C1-C2, resulting in improved CSF flow as well as venous outflow in chronic cerebral spinal venous insufficiency and multiple sclerosis.
The significance of cervical sagittal alignment for non-recovery after whiplash injury.
TLDR
This study indicates the existence of an association between the constitutional sagittal alignment of the cervical spine and the outcome after whiplash injuries.
Advanced magnetic resonance imaging of chronic whiplash patients: a clinical practice-based feasibility study
Background Whiplash injury is common following road traffic crashes affecting millions worldwide, with up to 50% of the injured developing chronic symptoms and 15% having a reduced working capability
The Cranial Cervical Syndrome Defined: New Hope for Postwhiplash Migraine Headache Patients - Cervical Digital Motion X-Ray, FONAR Upright® Weight-Bearing Multi-Position™ MRI and Minimally Invasive C1-C2 Transarticular Lag Screw Fixation Fusion
TLDR
It is hypothesized that lateral C1-C2 instability-induced transient vertebral artery compression explains the cranial cervical syndrome, and that fixation resolves the syndrome.
Fatal subarachnoid hemorrhage associated with internal carotid artery dissection resulting from whiplash trauma
TLDR
The case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery and intracerebral vascular structures following a hard braking maneuver is presented, indicating that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash.

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.
CONVERSION TO SYMPTOMATIC CHIARI I MALFORMATION AFTER MINOR HEAD OR NECK TRAUMA
TLDR
Minor head or neck trauma can precipitate the onset of symptoms in a small number of previously asymptomatic patients with Chiari I malformation, and health care professionals must be aware that neurological symptoms that persist or worsen after minor head or head trauma could indicate an underlying Chiari II malformation.
Asymptomatic Chiari Type I malformations identified on magnetic resonance imaging.
TLDR
It is suggested that the isolated finding of tonsillar herniation is of limited prognostic utility and must be considered in the context of all available clinical and radiographic data.
Acquired Chiari malformations: incidence, diagnosis, and management.
TLDR
It is concluded that a craniospinal pressure gradient creates a potential for cerebellar tonsil descent and it is recommended that ventriculoperitoneal shunting be performed in children with communicating hydrocephalus to avoid this potential complication.
Tonsillar herniation: the rule rather than the exception after lumboperitoneal shunting in the pediatric population.
TLDR
Although less than 5% of this study population required treatment for tonsillar herniation, the incidence of this complication was high in asymptomatic patients; MR imaging surveillance for patients with LP shunts is therefore recommended.
Chiari I malformations: clinical and radiologic reappraisal.
Clinical findings and magnetic resonance (MR) images in 68 patients with Chiari I malformations were retrospectively analyzed to identify those radiologic features that correlated best with clinical
Incidental finding of Chiari I malformation with progression of symptoms after head trauma: case report.
TLDR
This case describes a woman with chronic headaches who had an incidental finding of CMI with obstructive hydrocephalus and progression of symptoms after minor head trauma.
Presentation of a previously asymptomatic Chiari I malformation by a flexion injury to the neck.
TLDR
This unusual case suggests that in a trivial flexion injury to the neck sustained in a car accident, and where the standard diagnostic procedures are normal, the possibility of underlying congenital abnormality, such as Chiari I malformation should be considered.
Chiari Type II malformation: past, present, and future.
TLDR
Expeditious and knowledgeable evaluation and prompt surgical decompression of the hindbrain can prevent serious morbidity and mortality in the patient with myelomeningocele, especially those younger than 2 years old.
A late complication of CSF shunting: acquired Chiari I malformation
TLDR
This study contributes to the understanding of the underlying pathogenetic mechanisms of acquired Chiari type 1 malformation in cases of long-lasting supratentorial CSF shunting and provides a base for planning the best management, whether conservative or surgical.
