Pilocytic astrocytoma is a central nervous system tumor made up of star-shaped cells in your brain. It most often affects children and adults before age 20. This tumor is low-grade, which means it’s treatable and leads to a good prognosis if detected early.

Pilocytic astrocytoma (and its variant pilomyxoid astrocytoma) is a brain tumor that occurs most commonly in children and young adults (in the first 20 years of life).

2024年8月7日 · Pilocytic astrocytoma is a typically benign and slow-growing brain tumor that primarily affects children and young adults. This condition arises from astrocytes—the star-shaped cells that support nerve cells in the brain—and is most commonly found in the cerebellum, optic pathways, and hypothalamus region.

Pilocytic astrocytoma is a benign brain tumor that arises from astrocytes, the supportive cells in the nervous system. Normally, astrocytes are responsible for a variety of roles, including providing nutrients to neurons, maintaining the blood-brain barrier, and modulating neurotransmission (how neurons communicate with each other).

2024年11月7日 · Pilocytic astrocytomas, also known as juvenile pilocytic astrocytomas, are circumscribed astrocytic gliomas that typically occur in young patients. The majority of sporadic pilocytic astrocytomas arise from the cerebellum, whereas in the setting of neurofibromatosis type 1 (NF1), they often involve the optic chiasm and pathway.

Pilocytic astrocytomas are low-grade gliomas — a family of slow-growing tumors that arise from glial cells. They are the most benign and most treatable of the gliomas, with a cure rate of more than 90 percent.
