Essentials of Diagnosis

++

  • Classic triad2
    • Morning headache
    • Vomiting
    • Papilledema
  • Breast, lung, melanoma, and renal cell cancers are most likely to metastasize to brain tissue
  • Tumor can occur in any part of the brain; symptoms help identify location of tumor prior to diagnostic imaging
  • Confirmation is commonly done by stereotactic biopsy or craniotomy

++

General Considerations

++

  • Secondary metastatic deposits are more common in adults than in children
  • Frequency and location of pediatric brain tumors
    • Posterior fossa—most common frequency and location of pediatric brain tumors2
  • AIDS, neurofibromatosis, and systemic cancers predispose the patient to development of a tumor in the nervous system
  • Growth rates and invasiveness vary
    • Glioblastomas are highly malignant and invasive
    • Meningiomas are benign and slowly progressive

++

Demographics

++

  • Approximately 20,000 people die annually in the United States from a malignant glioma
  • Approximately 130,000 people who die with cancer have evidence of metastases to the brain
  • In children, primary brain tumors constitute the most common solid tumor and represent 25% to 30% of childhood neoplasms2
  • Medulloblastomas, spongioblastomas, optic nerve gliomas, and pinealomas occur most frequently before age 20
  • Meningiomas and glioblastomas occur more frequently after age 50
  • Glioblastomas occur ...
