Aprosencephaly and Cerebellar Dysgenesis

Prosencephaly Cerebellar Dysgenesis


Presentation

  • The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly.[books.google.com]
  • Griffith, Joan R.; Bada, Henrietta S. // Clinical Pediatrics;Jul/Aug2006, Vol. 45 Issue 6, p570 The article presents a case of chiari I malformation in a 17-year-old female who presented a 2-year history of chronic back pain.[connection.ebscohost.com]
  • Ultrasound , normal fetus - ventricle s of brain ... anencephaly ( aprosencephaly ) CNS malformation involving failure of closure of the cephalic end of the neural tube, resulting in absence of the forebrain and cerebrum ; rudimentary brainstem may be present[en.mimi.hu]
  • Except for the brain malformation other congenital abnormalities seem to be present more often in patients with aprosencephaly. In two patients (one with atelencephaly and one with aprosencephaly) an aberration of chromosome 13 was found.[link.springer.com]
  • In the present chapter we will discuss mostly congenital abnormalities.[tankonyvtar.hu]
Rigor

Pathologist
  • All clinicians and scientists interested in birth defects, including pediatricians, geneticists, genetic counselors, obstetricians, and pediatric pathologists, will find this book to be an invaluable source of information.[books.google.com]
Suggestibility
  • The similarity of these cases, coupled with parental consanguinity, suggests a primary malformation in brain development due to the homozygous representation of a mutant allele.[ncbi.nlm.nih.gov]
  • There is abnormal loss of fetal hemisphere definition, suggesting a bilateral global monoventricle with preservation of superficial cortical surface (Figure 3).[neuroradiologysilan.com]
  • A review of the literature regarding Chiari II malformations and holoprosencephaly suggests that a disturbance to the mesenchyme in early embryologic life may be the cause of both malformations.[ajnr.org]
  • We suggest that phenotype-genotype correlations for TGIF and GLI2 should be analysed in larger series.[hal.inserm.fr]
  • Since calcific vasculopathy is a common accompaniment of other inflammatory diseases of the central nervous system, its presence in this case suggests that destructive processes may be involved in the genesis of some cases of aprosencephaly.[link.springer.com]

Treatment

  • The anomalies are organized by anatomical system and presented in a consistent manner, including details of the clinical presentation, epidemiology, embryology, treatment and prevention for each anomaly.[books.google.com]
  • Treatment depends upon the problem. In many cases, treatment only helps with symptoms. It may include antiseizure medicines, shunts to drain fluid from the brain, and physical therapy. There are head malformations that do not involve the brain.[icdlist.com]
  • Treatment depends upon the underlying disorder and the severity of symptoms.[en.wikipedia.org]
  • There is no causal treatment, only symptomatic. 2.1.2.[tankonyvtar.hu]

Prognosis

  • Prognosis [ edit ] The prognosis of this developmental disorder is highly based on the underlying disorder. Cerebellar hypoplasia may be progressive or static in nature.[en.wikipedia.org]
  • Rarely, dural sinus thromboses arise from an underlying dural arteriovenous fistula and have a worse prognosis. 20 Bilateral internal carotid artery territory destruction leading to hydranencephaly is one of the most severe insults to the brain.[jaocr.org]
  • Despite counseling regarding the infant's poor prognosis, the mother requested further treatment for the child's intermittent apneic episodes.[ajnr.org]
  • If it is recognised early, prognosis for operated patients is good. 2.5.4. Neurofibromatosis (von Recklinghausen disease) It is a relatively common congenital disorder of autosomal dominant inheritance.[tankonyvtar.hu]
