Craniopharyngioma is a type of central nervous system (CNS) tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it is usually fast-growing and can spread to other parts of the body. A benign tumor means the tumor is usually slower-growing but will not spread. Craniopharyngioma is a benign tumor that is usually slow-growing and very unlikely to spread.
About the central nervous system
The brain and spinal cord make up the CNS, where all vital functions of the body are controlled. The brain is the center of thought, memory, and emotion. It controls the five senses, which include smell, touch, taste, hearing, and sight. It also controls movement and other basic body functions, including consciousness, heartbeat, circulation, and breathing. The spinal cord is made up of nerves that carry information from the body to the brain and from the brain to the body. When a tumor grows in the CNS, it can affect a person’s thought processes and/or movements. A tumor in the CNS can sometimes be difficult to treat because the tissue around the tumor may be vital to the body’s functioning. However, treatment for craniopharyngioma has a high rate of success.
Craniopharyngioma starts near the pituitary gland in a part of the brain called the suprasellar region. This region is the area of the brain just above the sella. The sella is the part of the skull where the pituitary gland is located. The pituitary gland is an important gland in the brain and is often called the “master endocrine gland” because it produces several different hormones that affect how the body functions.
Craniopharyngioma is a slow-growing tumor that can grow for many years before it is found. It can be solid and/or cystic, which means the tumor has a closed pouch or sac that contains fluid made by the tumor. The solid part often contains areas of calcium that can easily be seen on a CT scan. The cystic part of the tumor often contains very high amounts of protein.
