G53.3: Multiple cranial nerve palsies in neoplastic disease

Various nerves run from the brain to the sensory organs in the head, and to organs in the body. These nerves are called cranial nerves. These nerves are important in seeing, tasting or hearing, for example. But the cranial nerves also control important functions in the body, such as in the lungs and heart.

The damage to your cranial nerves has resulted from abnormal growth of tissue.

When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.
