Childhood Ependymoma Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Childhood Ependymoma
Once an ependymoma forms, areas of the brain that may be affected include:
- Cerebrum: The largest part of the brain, at the top of the head. The cerebrum controls thinking, learning, problem-solving, speech, emotions, reading, writing, and voluntary movement.
- Cerebellum: The lower, back part of the brain (near the middle of the back of the head). The cerebellum controls movement, balance, and posture.
- Brain stem: The part that connects the brain to the spinal cord, in the lowest part of the brain (just above the back of the neck). The brain stem controls breathing, heart rate, and the nerves and muscles used in seeing, hearing, walking, talking, and eating.
- Spinal cord: The column of nerve tissue that runs from the brain stem down the center of the back. It is covered by three thin layers of tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones). Spinal cord nerves carry messages between the brain and the rest of the body, such as a message from the brain to cause muscles to move or a message from the skin to the brain to feel touch.
The cause of most childhood brain tumors is unknown.
The signs and symptoms of childhood ependymoma are not the same in every child.
Signs and symptoms depend on the following:
- The child's age.
- Where the tumor has formed.
Signs and symptoms may be caused by childhood ependymoma or by other conditions. Check with your child's doctor if your child has any of the following:
Tests that examine the brain and spinal cord are used to detect (find) childhood ependymoma.
The following tests and procedures may be used:
- Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
- Neurological exam: A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person's mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam.
- MRI (magnetic resonance imaging) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the brain and spinal cord. A substance called gadolinium is injected into a vein and travels through the bloodstream. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Lumbar puncture: A procedure used to collect cerebrospinal fluid (CSF) from the spinal column to check for cancer cells. This is done by placing a needle into the spinal column. This procedure is also called an LP or spinal tap.
Lumbar puncture. A patient lies in a curled position on a table. After a small area on the lower back is numbed, a spinal needle (a long, thin needle) is inserted into the lower part of the spinal column to remove cerebrospinal fluid (CSF, shown in blue). The fluid may be sent to a laboratory for testing.
