Skull Base Tumor

Skull Base Tumor Symptoms and Causes

Skull base brain tumors are the growth of abnormal or uncontrolled cells in the part of the brain that meets the base of the skull. Most skull base tumors are primary, meaning that they develop in the brain and do not spread to other parts of the body. Most of the tumors that occur at the skull base are benign (not cancerous), yet they can be life-threatening because they are invasive. Some of the various symptoms of a skull base tumor are headaches, vomiting, drowsiness, seizures, dizziness, vision and hearing loss, speech difficulties and loss of sensation in an arm or leg. Physicians do not know what causes skull base tumors.
