Methods The authors present their 12-year experience with this group of patients. Results Fifteen patients (3.7%) were identified. At surgery, many were found to have physical barriers to CSF flow near the foramen magnum. [doi.org]

Presentation Chiari type I [ 5 ] The presentation of this condition depends upon the severity of the herniation and associated other features. [patient.info]

• Plethora

  Conclusions There exists a plethora of diseases affiliated with CM-I, many of which have been mentioned in this article and certainly more to be discovered in the future. [doi.org]

• Ulcer

  […] cutaneous disorders such as neurofibromatosis Type I. 36 Equally mysterious is the association of CM-I with macrocephaly-cutis marmorata telangiectatica congenita, 73 which is characterized by benign spider nevuslike telangiectasias and superficial ulcerations [doi.org]

  Coughing, laughing, bending forward, sneezing or looking up can worsen the headache. Headache may be confused with migraine. Neck Pain – often pressure like and radiating down the spine and across the shoulders. [web.archive.org]

  Accordingly, headache and neck pain in Chiari I are often exacerbated by cough and Valsalva maneuver. Hydrocephalus occurs less frequently. [emedicine.medscape.com]

  The drummer sought medical attention after she started experiencing symptoms including dizziness, insomnia, headaches, tingling/numbness in her hands and a stiff neck. [nme.com]

All patients underwent a detailed medical and neuroradiological workup that included an assessment of articular mobility. [doi.org]

The prognosis otherwise depends on severity of the malformation, associated neurological abnormalities and complications. There has been some improvement in prognosis with improved diagnostic and surgical techniques. [patient.info]

Prognosis and Outcomes The key to good prognosis of Chiari II malformation is early recognition of symptoms and early treatment. Patients with less severe symptoms at diagnosis are much more likely to improve with surgical intervention. [csfinfo.org]

Prognosis Long-term prognosis for persons with Arnold-Chiari I malformations is excellent. Full recovery from surgery may take several months. [encyclopedia.com]

Without an obvious CM-I, other etiologies of a spinal syrinx must be conclusively ruled out. Only then can one reasonably expect to ameliorate the clinical course of these patients via posterior fossa decompression. [doi.org]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

Although studies of etiology are few, an increasing number of specific genetic syndromes are found to be associated with Chiari malformations. Management primarily targets supportive care and neurosurgical intervention when necessary. [medlink.com]

Contraindications Surgical decompression of foramen magnum is contraindicated when tonsillar herniation is caused by etiologies other than Chiari malformation, such as mass lesions in the posterior fossa or CSF hypotension syndrome. [emedicine.medscape.com]

Epidemiology Chiari type I Retrospective investigation of brain MRIs has found a prevalence of 1 in 1,280 individuals [ 5 ]. It tends to present earlier if there is syringomyelia. [patient.info]

Epidemiology It used to be said that Chiari malformations are rare, but with routine use of MR imaging Chiari malformation is discovered with increasing frequency. [physio-pedia.com]

Epidemiology The most common Chiari malformation is type I and has been estimated to occur in 1 in 1000 births. The majority of these cases are asymptomatic. [emedicine.medscape.com]

While the final outcome of CM-I may be the same, the strength of the correlation and pathophysiological mechanisms of each differs greatly and some may be spurious associations. [doi.org]

[…] of 3 pathophysiological consequences of the disordered anatomy: (1) compression of medulla and upper spinal cord, (2) compression of cerebellum, and (3) disruption of CSF flow through foramen magnum. [emedicine.medscape.com]

Renewed effort to address current deficits in Chiari research involves work groups targeted at pathophysiology, symptoms and diagnosis, engineering and imaging analysis, treatment, pediatric issues, and related conditions. [medlink.com]

Even if symptoms do not improve significantly, surgery might prevent existing symptoms from worsening. [4] Last updated: 9/11/2017 The long-term outlook depends on the nature of the malformation and the symptoms present in each person. [rarediseases.info.nih.gov]

Prevention There is no known way to prevent Chiari malformation. Genetic counseling may help parents of a child with this condition to determine the risk in future children. References: Chiari malformation fact sheet. [cancercarewny.com]

This limitation alone could prevent most work. [disabilitysecrets.com]

Surgery is necessary to prevent life-threatening conditions and death. General symptoms The range and severity of symptoms depend on the type of Chiari malformation and individual factors. [medicalnewstoday.com]
