Presentation

  • Presentation: The most common presentation of posterior fossa tumors in children is symptomatic elevated ICP secondary to obstructive hydrocephalus . Focal signs are less common.[ispn.guide]

Prognosis

  • This volume mainly contains information on the diagnosis, therapy, and prognosis of brain tumors. Insights on the understanding of molecular pathways involved in tumor biology are explained, which should lead to the development of effective drugs.[books.google.es]
  • Infratentorial GBM presents with limited surgical treatment options and a poorer prognosis. Computational studies have shown a strong connection between the array layout and the field distribution within the supratentorial region.[academic.oup.com]
  • Prognosis” refers to the probable course and outcome of the disease. Physicians reference one or more clinical studies to obtain their prognosis statistics.[cern-foundation.org]
  • On the whole, the long term prognosis is better in children than adults. Incidence The incidence of pediatric brain tumors is roughly 3.3 cases per 100,000 children in North America.[pedsoncologyeducation.com]
  • However, there are different opinions among doctors about importance of grade in determining the prognosis for children diagnosed with grade II ependymoma or anaplastic ependymoma (WHO grade III).[cancer.net]

Pathophysiology
