The brain stem is the part of the brain connected to the spinal cord. It is located in the lowest part of the brain, just above the back of the neck. The brain stem is the part of the brain that controls breathing, heart rate, and nerves and muscles used in seeing, hearing, walking, talking, and eating. Most childhood brain stem gliomas are pontine gliomas, which form in a part of the brain stem called the pons.
Although cancer is rare in children, brain tumors are the most common type of childhood cancer other than leukemia or lymphoma.
This summary refers to the treatment of primary brain tumors (tumors that begin in the brain). Treatment for metastatic brain tumors, which are tumors formed by cancer cells that begin in other parts of the body and spread to the brain, is not discussed in this summary. Brain tumors can occur in both children and adults; however, treatment for children may be different than treatment for adults. (Refer to the PDQ treatment summary on Adult Brain Tumors for more information.) The cause of most childhood brain tumors is unknown. The symptoms of childhood brain stem glioma vary and often depend on the child’s age and where the tumor is located.
These and other symptoms may be caused by a brain stem glioma. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:
Loss of balance and trouble walking.
Vision and hearing problems.
Morning headache or headache that goes away after vomiting.
Nausea and vomiting.
Unusual sleepiness or change in energy level.
