Comprehending Brain Tumors
Brain tumors are abnormal growths in the brain that can disrupt its function, depending on their location and size.
What Exactly Are Brain Tumors?
These are abnormal brain cell growths. They occur when cells proliferate excessively, disrupting brain function. Some are benign, while others are malignant and may metastasize.
Categories of Brain Tumors
Brain tumors vary based on their originating cells and behavior. The main types include:
- Gliomas originate from glial cells and are the most common brain tumors, ranging from low to high grades, with glioblastoma being the most aggressive.
- Meningiomas: Tumors that develop from the brain’s protective membranes, typically benign.
- Pituitary adenomas are tumors in the pituitary gland that can alter hormone production.
- Schwannomas originate from Schwann cells and can impair nerves responsible for hearing and balance.
Understanding gliomas is crucial, as their behavior and prognosis can differ. Symptoms depend on the tumor type, location, and growth rate, and may include headaches, seizures, or cognitive and sensory issues.
Features of Pilocytic Astrocytoma
Pilocytic astrocytomas are characterized by their appearance and typical location in the brain, mainly affecting children and young adults. They commonly develop in the cerebellum and optic pathways and tend to grow slowly with limited spread, facilitating diagnosis and treatment.
Tissue Structure and Location
These tumors consist of elongated, hair-like glial cells that form a fibrous network, a characteristic feature of this tumor type. They are often found in the cerebellum, influencing surgical and treatment approaches.
They contain a cystic component with a solid core, aiding in diagnosis. The presence of Rosenthal fibers and eosinophilic granular bodies helps distinguish these tumors from others. Overview of Cerebral Pilocytic Astrocytoma
