Astrocytoma
Histological appearance
Pilocytic
Pilocytic astrocytomas are relatively common. They are also known as Grade I gliomas. Pilocytic astrocytomas are well differentiated and are essentially just hyperplastic astrocytes.
Desmoplastic
I don't know anything about these.
Subependymal Giant Cell Astrocytomas
These are big.
Metastasis
Astrocytomas are not likely to metastasize.
Interventions
As with all brain malignancies, interventions are selected largely upon anatomical location. Surgical and non-surgical interventions are possible.
Prognosis
As compared to pediatric medulloblastomas and glioblastomas, prognosis for pilocytic astrocytoma is good. Patients are expected to live in xyz% of cases.
