Hemihypertrophy and the Chiari I Malformation
Pediatric Neurosurgery, 2003We report two children with hemihypertrophy and Chiari I malformation (CIM) and review the extant medical literature regarding CIM and overgrowth disorders. We propose that these two entities do not represent a spurious association but rather share a common dysembryology of mesoderm.

Chiari in the Family: Inheritance of the Chiari I Malformation
Pediatric Neurology, 2006This report presents three families with Chiari malformation type I that became symptomatic during childhood: a mother and son; a set of monozygotic twins; and two half-siblings and their two maternal cousins. These children presented with various symptoms, including headache, stiff neck, and swallowing difficulty.

Orthostatic Intolerance and Chiari I Malformation
Neurosurgery Clinics of North America, 2023Individuals with Chiari malformation can present with symptoms of fatigue, lightheadedness, and syncope-the cardinal features of orthostatic intolerance. Similar orthostatic symptoms can complicate the clinical course following Chiari decompression. The presence of orthostatic intolerance in patients with Chiari malformation is not surprising given the

Chiari I malformation in patients with RASopathies
Child's Nervous System, 2021Chiari I malformation (CIM) is a common pediatric neurologic anomaly which could be associated with a variety of genetic disorders. However, it is not always clear whether the observed associations between CIM and RASopathies are real or random. The knowledge of the real association could provide useful guidance to clinicians.

Clinical Manifestations of Chiari I Malformation
Neurosurgery Clinics of North America, 2023Chiari 1 malformation (CM1) includes a spectrum of clinical manifestations. These signs and symptoms result from compression at the cervicomedullary junction and alteration in cerebrospinal fluid dynamics thus affecting several structures above, at, and below the cervicomedullary junction.

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)

Clinical features of Chiari I malformations
Child's Nervous System, 2004With the advent of MRI, the diagnosis of Chiari I malformation is being made in younger patients, often with minimal or no neurologic symptoms.The symptoms and signs of a Chiari I malformation may be related to the compression of neural and/or dural structures at the cranio-cervical junction or may be related to the associated syringomyelia.

As with many pathologies, the course of our understanding of the Chiari I malformation (CIM) has developed extensively over time. The early descriptions of the Chiari malformations by Hans Chiari in 1891 opened the door for future classification and research on this topic.

Syringomyelia associated with Chiari I malformation
Neurological Sciences, 2009An 18-year-old man with progressive paraparesis, thermal hypoesthesia, sweating abnormalities, bladder dysfunction, severe orthostatic hypotension, bilateral Babinski sign, underwent a brain MRI scan that showed downward displacement of cerebellar tonsils through the foramen magnum, consistent with Chiari I malformation, compression of the brainstem ...

History of Chiari type I malformation
Neurological Sciences, 2011Chiari type I malformation (CIM) was first described in the late 19th Century. However, it still raises a great interest among the scientific Community because of the increasing number of diagnosed cases, the still unclear pathogenesis and natural history and the different options in the surgical management.
