Excellent prognosis among posterior fossa tumors in children
Most posterior fossa tumors in children have a poor prognosis except for one, which has an excellent prognosis. What is it?
Juvenile cerebellar pilocytic astrocytoma has virtually a 100% 5-year survival rate.
This tumor develops in the cerebellar hemispheres of school-aged children. Histologically, the tumor cells are hair-like (pilocytic).
The tumor is classified as a grade 1 neoplasm, which is a well-circumscribed neoplasm without local invasiveness. Complete resection is curative.
