Chiari type I malformation in children
The Journal of Pediatrics, 1989We reviewed the recent experience at Texas Children's Hospital by examining the records of 11 children who underwent suboccipital decompression for symptomatic Chiari type I malformation. Presenting complaints included neck pain (1 child), scoliosis (4 children), back pain (1 child), torticollis (1), motor dysfunction (1), and apnea (3 children ...

Journal of Neurosurgery: Pediatrics, 2007
The study in this issue by Sgouros and colleagues comes from a unit with a long and distinguished history of interest and work in the area of hindbrain hernias. The authors build on this background and provide the reader with evidence of a skull base that is wider and has a steeper angle with the clivus in patients with Chiari malformation Type I (CM-I)

Hydrocephalus and Chiari type I malformation
Child's Nervous System, 2011[corrected] Hydrocephalus has been related to Chiari type I malformation (CIM) for a long time. The pathogenesis of this association is complex and still debated.A supratentorial hypertensive hydrocephalus may cause CIM, exerting pressure from above. Another pathogenetic hypothesis is based on the clinical and radiological data from patients affected ...

Analysis of the Prechiasmatic Sulcus in Chiari Malformation Type I
World Neurosurgery, 2023To assess morphologic features of the prechiasmatic sulcus (PS) in Chiari malformation type I (CM-I).Computed tomography images were obtained in patients with CM-1 (mean age: 21.26 ± 16.46 years; sex: 25 females and 17 males) and 58 healthy control subjects (mean age: 28.12 ± 22.60 years; sex: 29 females and 29 males).

Scoliosis in patients with Chiari malformation type I
Child's Nervous System, 2019The literature about the association between Chiari malformations (CMs) and scoliosis has been growing over the last three decades; yet, no consensus on the optimal management approach in this patient population has been reached. Spinal anomalies such as isolated syrinxes, isolated CM, and CM with a syrinx are relatively common among patients with ...

Chiari I malformation and neurofibromatosis type 1
Pediatric Neurology, 2004Single case reports exist in the medical literature of patients with tonsillar ectopia, i.e., the Chiari I malformation and neurofibromatosis type 1. However, large series of patients with either of these entities have not been examined for the presence of both defects.

Imaging of Chiari Type I Malformation and Syringohydromyelia
Neurologic Clinics, 2014Chiari malformations are anatomic anomalies that comprise a broad spectrum of neurologic conditions. The most common malformation, a Chiari type I malformation, can present with a variety of signs and symptoms, most frequently an occipital Valsalva-induced headache.

Evolutionary hypothesis for Chiari type I malformation
Medical Hypotheses, 2013Chiari I malformation (CM-I) is classically defined as a cerebellar tonsillar herniation (≥5 mm) through the foramen magnum. A decreased posterior fossa volume, mainly due to basioccipital hypoplasia and sometimes platybasia, leads to posterior fossa overcrowding and consequently cerebellar herniation. Regardless of radiological findings, embryological

Fourth Ventricle Enlargement in Chiari Malformation Type I
World Neurosurgery, 2020How Chiari malformation type I (CM-I) affects posterior fossa brain structures and produces various symptoms remains unclear. The fourth ventricle is surrounded by critical structures required for normal function. The foramen of Magendie can be obstructed in CM-I; therefore, fourth ventricle changes may occur.

Headache Associated With the Chiari Type I Malformation.
Headache: The Journal of Head and Face Pain, 1993SYNOPSIS The main purpose of the present study was to define and understand more clearly the headache, and in particular the long‐lasting attacks or continuous pain associated with the Chiari type I malformation. Of 34 patients with the malformation, the 20 patients who had or had had headache problems were interviewed according to a ...
