Pediatric Pilocytic Astrocytoma

Pilocytic astrocytomas are one of the most common brain tumors found in children. Usually, this type of tumor is benign (non-cancerous). They typically grow slowly and don’t spread to surrounding brain tissue. At Children’s Health, neurosurgeons, radiologists and oncologists from UT Southwestern Medical Center are top experts in treating pediatric cancer. We have years of specialized training and expertise in helping children like yours overcome cancer.

What is Pediatric Pilocytic Astrocytoma?

Pilocytic astrocytomas start in astrocytes, which are brain cells that help your central nervous system do tasks like store energy, absorb water and repair tissues. Pilocytic astrocytomas are part of a group of tumors called low-grade gliomas. These tumors grow slowly and are less likely to spread than other types of brain tumors. They’re most common in children between ages 5 and 8.

How is Pediatric Pilocytic Astrocytoma diagnosed?

First, your child will have an MRI, which takes images of their brain. MRIs show us if your child has a tumor, where it's located and how big it is.

If we find a tumor, we’ll take a sample of it, called a biopsy. A biopsy allows us to see what type of tumor your child has and if it is cancerous.

After taking detailed pictures and a biopsy of your child’s brain tumor, our team of experts will work together to create a custom treatment plan.

What causes Pediatric Pilocytic Astrocytoma?

Scientists don’t know exactly what causes pilocytic astrocytoma. Genetics may play a part. Having a family member who has a pilocytic astrocytoma may make you more likely to have one.

Frequently Asked Questions

  • Do pilocytic astrocytomas come back?

    Pilocytic astrocytomas can come back after they are treated, but we do everything we can to prevent that. This includes using radiation after surgery to target any tiny fragments of tumor left after surgery. We also use specialized chemotherapy drugs that target a tumor’s growth pathways to eliminate it and keep it from coming back.
