Arnold-Chiari Malformation Type I

Syringomyelia


Presentation

  • Abstract A case review of a healthy 3-year-old toddler with a chief complaint of sleep-disordered breathing is presented. The child underwent a pneumogram sleep study with significant abnormal findings.[ncbi.nlm.nih.gov]
  • We present the first reported case of a parturient with both Arnold-Chiari malformation type I and sickle cell disease who presented to labor and delivery with acute pain crisis and who subsequently received epidural labor analgesia and underwent successful[ncbi.nlm.nih.gov]
  • Balance difficulties, vertigo and dizziness also may be present. Some people may have cranial nerve compression.[asap.org]
  • This patient presented with symptoms induced by a cervical lesion at 65 years of age.[nature.com]
  • We suggest that brain and cervical spine MRI should be performed if neurological symptoms are present.[journals.lww.com]
Anxiety Disorder
  • PRS and anxiety symptoms should be explored in ACM patients to allow better prevention of psychosis and anxiety disorders.[ncbi.nlm.nih.gov]
  • . : Anxiety disorder in a case of Arnold-Chiari malformation. J Psychiatry Neurosci. 1993; 18 (2): 67–8. PubMed Abstract Free Full Text 8.[f1000research.com]
Psychiatric Symptoms
  • BACKGROUND: There are some case reports that highlight the association of Arnold-Chiari malformation (ACM) with psychiatric symptoms.[ncbi.nlm.nih.gov]
  • During the same period she started to experience psychiatric symptoms, at the beginning characterized by excessive anxiety, epigastric discomfort, restlessness and insomnia.[f1000research.com]
Auditory Hallucination
  • We believe, indeed, that the patient’s psychotic symptoms, especially auditory hallucinations and visual pseudo-hallucinations, are due to the organic pathology.[f1000research.com]
Spastic Quadriplegia
  • Spastic quadriplegia occurring as a result of brain stem compression in osteopetrosis is uncommon. The association of Type 1 Arnold Chiari malformation with osteopetrosis resulting in brain stem compression syndrome is an extremely rare entity.[ncbi.nlm.nih.gov]
Spastic Paralysis
  • It can lead to a spastic paralysis or weakness of the arms and/or legs as well as numbness and tingling. Because the Chiari malformation is on the midline, usually symptoms are bilateral, meaning they occur in both sides of the body.[nervous-system-diseases.com]
Akathisia
  • She was prescribed Amisulpride tablets (300 mg/day) and Paroxetine tablets (40 mg/day), but after 5 days the patient developed extrapiramidal symptoms and akathisia.[f1000research.com]
Long Tract Signs
  • Upper spinal cord compression will cause long tract signs (hyperreflexia, Hoffman’s sign, clonus and Babinski’s reflex).[neckandback.com]
Aura
  • She also denied symptoms such as nausea, vomiting, sinus congestion, nasal drainage, aura, photophobia, phonophobia, chest pain, or palpitations. She denied having a history of chronic headache prior to the onset of these symptoms.[consultant360.com]

Treatment

  • INTRODUCTION: Several different surgical techniques have been used in the treatment of patients with symptomatic Arnold-Chiari malformation type 1 (ACM-1) with or without syrinx.[ncbi.nlm.nih.gov]

  • What Are Some Common Treatments? If a patient is confirmed to have a significant Type I Arnold-Chiari malformation treatment usually depends on symptoms and the patient's preferences. Asymptomatic patients usually do not require treatment.[nervous-system-diseases.com]

Prognosis

  • 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]
  • […] malformation: type I: herniation of the cerebellar tonsils associated with syringomyelia type II: herniation of the cerebellar vermis and tonsils associated with meningomyeloceles and hydrocephalus Links: types clinical features investigations treatment prognosis[gpnotebook.co.uk]
  • , Prevention, and Comlications Prognosis range widely depending on type and severity of anatomic abnormality some children with type I function normally, while type III has low survival rate Prevention no preventive measures are available at this time[medbullets.com]
  • 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]

Etiology

  • 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]
  • As almost all neonatal patients with Chari II have a myelomeningocele, it has been suggested that the underlying etiology is that of in utero CSF leak due to open spinal dysraphism.[radiopaedia.org]
  • […] compression of cerebellum or disruption of cerebrospinal fluid flow through the foramen magnum The pathophysiology of Chiari type II malformation is more complex; although compressive mechanisms likely play a role, additional mechanisms may be functional Etiology[pathologyoutlines.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]

Pathophysiology

  • Pathophysiologically this group is consistent with the second or third mechanism. These patients typically have a low or normal awake pCO 2 [ 10 ].[mrmjournal.biomedcentral.com]
  • Type II The pathophysiology of Chiari II is more complex. Although compressive mechanisms likely play a role, as in Chiari I, additional mechanisms may be operative in Chiari II.[physio-pedia.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]
  • Symptoms of Chiari type I malformation develop due to compression of medulla and upper spinal cord, compression of cerebellum or disruption of cerebrospinal fluid flow through the foramen magnum The pathophysiology of Chiari type II malformation is more[pathologyoutlines.com]
