Internal Capsule Tumors

Internal capsule tumors are abnormal growths that occur within the internal capsule of the brain. The internal capsule is a region of white matter in the brain that acts as a pathway for nerve fibers traveling to and from the cerebral cortex. When tumors develop in this area, they can disrupt the normal function of these nerve pathways, leading to various symptoms and complications.

Types of Internal Capsule Tumors:

1. Gliomas: These are tumors that originate from glial cells, which provide support and protection for neurons in the brain.
2. Metastatic Tumors: These tumors occur when cancer cells from other parts of the body spread to the internal capsule.
3. Meningiomas: These tumors develop from the meninges, the protective membranes that surround the brain and spinal cord.
4. Pituitary Tumors: These tumors arise from the pituitary gland, which is located at the base of the brain.
