Brain tumors are of several kinds. They can be found in adults and children equally. Certain brain tumors are genetically related, being part of a certain disease. Some others might just arise without any known cause.

The brain tumors which arise below the cerebrum are known as infratentorial brain tumors. They are called that because they exist below the brain sheath known as tentorium. These tumors take place in the part of the brain known as cerebellum and the brain stem. The cerebellum mostly controls the balance function in your body whereas the brain stem is responsible for breathing, heart funtion, consciousness, hunger and involuntary muscle movement etc.

The brain tumors arising above the tentorium sheath are called supratentorial tumors. They usually exist in the part of the brain known as cerebrum which is responsible for movement coordination, judgement, problem solving, learning, reasoning, and personality etc.

Usually the brain tumors could be supratentorial or infratentorial in nature in an adult human, but in children they are mostly infratentorial. It is a rare case if a child comes up with a supratentorial brain tumor.
