Central nervous system tumor

(Redirected from Brain tumor)

This page is for adult patients. For pediatric patients, see: Central nervous system tumor (peds).


  • Metastatic tumors more common than primary CNS in adults
  • CNS tumors are second most common pediatric cancer, leading cause of cancer-related death in children
  • Most primary tumors in children are infratentorial, whereas most infratentorial masses in adults are metastases

Clinical Features

Differential Diagnosis


  • CT head
  • MRI required for small tumors or areas not well visualized on CT (e.g. posterior fossa)
  • Evaluate for other causes of symptoms (i.e. stroke, metabolic derangement, ICH)


  • See elevated ICP
    • Corticosteroids (reduce tumor capillary permeability, inflammatory cytotoxicity)
    • Elevate head of bed to 30 degrees, provide adequate sedation in intubated patients
    • Maintain cerebral perfusion (euvolemia, vasopressors if necessary)
    • Consider osmotherapy (e.g. hypertonic saline, mannitol)
  • Treat seizure with benzodiazepines +/- AEDs, prophylactic AEDs are not recommended
  • Consult neurosurgery
