Astrocytoma
Astrocytoma[edit | edit source]
Astrocytoma is a type of tumor that originates in the brain or spinal cord and is characterized by astrocytic differentiation. Astrocytomas are part of a group of tumors known as gliomas and vary widely in their behavior and prognosis.
Types of Astrocytomas[edit | edit source]
Astrocytomas are classified into several types, each with distinct characteristics:
Pilocytic Astrocytoma[edit | edit source]
A relatively benign form of astrocytoma typically found in children and young adults.
Diffuse Astrocytoma[edit | edit source]
A slow-growing tumor that infiltrates surrounding brain tissue.
Anaplastic Astrocytoma[edit | edit source]
A more aggressive and malignant form, characterized by rapid growth.
Pleomorphic Xanthoastrocytoma[edit | edit source]
A rare tumor usually occurring in young adults, with a relatively favorable prognosis.
Subependymal Giant Cell Astrocytoma[edit | edit source]
Typically associated with tuberous sclerosis, these tumors are generally benign.
Symptoms[edit | edit source]
Symptoms of astrocytomas can vary based on the tumor's location and size and may include:
- Headaches
- Seizures
- Neurological deficits (e.g., speech or vision problems)
Diagnosis[edit | edit source]
Diagnosis typically involves imaging studies like MRI or CT scans and a biopsy to confirm the tumor type.
Treatment[edit | edit source]
Treatment depends on the type and grade of the tumor and may include:
- Surgery
