Common brain tumors in infancy (i.e. under one year of age) are quite different from those of brain tumors in adulthood. Most are located in the supratentorial region (~65%) and they carry a poor prognosis.
The frequency of these tumors varies according to studies, but the most common brain tumors include 1-3:
- anaplastic astrocytoma
- medulloblastoma
- ependymoma
- atypical teratoid/rhabdoid tumor (AT/RT)
- choroid plexus papilloma
- intracranial teratoma
- embryonal tumors with multilayered rosettes (previously known as CNS PNET)
- adamantinomatous craniopharyngioma
