  • Gliosis will develop if the insult is late enough, usually thought to be after the start of the third trimester, although perhaps insults as early as 20 weeks of gestation may result in gliosis 11.[radiopaedia.org]
  • On the other hand, the acquired types are usually single and unilateral, with borders usually showing evidence of old necrotic foci, gliosis, connective scar tissue, and meningeal thickening.[mdedge.com]
  • More mature brains have a greater capacity to develop a glial scar (gliosis) around the cyst. 13 After approximately 30 weeks’ gestation, there is a greater chance of reactive glial scarring. 14 Hydranencephaly represents an extreme form of bilateral[radiologykey.com]


  • Neurologists and neurobiologists, psychologists, psycholinguists, psychiatrists, and special educators will find here a guide to more enlightened understanding and more effective treatment of dyslexia.[books.google.com]

  • Treatment Treatment is addressed to alleviating symptoms, not to curing the underlying problem, as there is no treatment to induce the brain to grow missing sections of the cerebrum.[encyclopedia.com]
  • Treatment of hydranencephaly is supportive, with shunting if head growth is excessive. Schizencephaly, which some experts classify as a form of porencephaly, involves the presence of abnormal slits, or clefts, in the cerebral hemispheres.[msdmanuals.com]


  • It is important to separate out enlarged third ventricles from true arachnoid cysts, as the long-term prognosis of these patients will differ.[fetalsono.com]
  • What is the prognosis? The prognosis for individuals with porencephaly varies according to the location and extent of the lesions.[bridges4kids.org]
  • The prognosis in these patients is guarded. Significant mental and motor retardation occurred in nearly all cases. Received September 21, 1973. Accepted February 1, 1974.[pediatrics.aappublications.org]
  • Long-term prognosis depends on the size and location of the lesions, and whether there is a hereditary thrombophilia or vasculopathy. The neonate should be evaluated after birth by a pediatric neurologist. Follow-up brain imaging is recommended.[mhmedical.com]
  • Each individual's prognosis will depend on the location and severity of the lesions on their cerebrum. Resources BOOKS Graham, David I. and Peter L. Lantos. Greenfield's Neuropathology, 6th edition. Bath, UK: Arnold, 1997.[encyclopedia.com]


  • Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.[icd10coded.com]
  • Since Heschl's first description, the term "porencephaly" has been widely used to describe etiologically different brain cavities communicating with either the subarachnoid space or the lateral ventricles.[medlink.com]
  • The same risk factors that cause neonatal and pediatric stroke account also for fetal stroke but no specific etiology is found in 50% of cases. The end result of fetal stroke may be a fluid filled cavity (porencephaly).[neuropathology-web.org]
  • The etiological basis could not be determined in most cases.[docslide.net]
  • These cases lead us to believe that hypoxic ischemic damage of the brain is the etiology of porencephalic cyst when associated with cerebral hemiatrophy or when adjacent ulegyria is present.[link.springer.com]


  • The distinguished contributors to this volume examine epidemiological and clinical issues that may make the developing brain more vulnerable to environmental and genetic influences, which can in turn lead to abnormal brain plasticity and behavior.[books.google.com]
  • Epidemiology: Arachnoid cysts correspond to about 1% of all intracranial lesions in the general population and about 3% in the pediatric population.[thamburaj.com]

  • Alternate names include epithelial cyst, ependymal cyst, choroid cyst, choroidal-epithelial cyst, and glioependymal cyst. 1 Pathophysiology Initially, neuroepithelial cysts were thought to arise by evagination and sequestration of ependyma or choroidal[radiologykey.com]

  • Treatment includes physical therapy for rigidity, spasticity, or movement difficulties; medication to prevent seizures ; and, if necessary, the installation of a shunt or drain to remove excess cerebrospinal fluid from the inside of the skull.[encyclopedia.com]
