D33: Benign neoplasm of brain and other parts of central nervous system
D33.3: Benign neoplasm: Cranial nerves
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.
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. The tumor you have is benign. Benign tumors do not destroy the healthy tissue and do not spread throughout the body. However, a tumor can crowd out the healthy tissue.
When you have a tumor in a cranial nerve, you may have various symptoms. You may have problems with your sight, hearing or sense of smell. You may also no longer be able to feel anything in certain parts of your face. You may no longer be able to move certain muscles properly. It is also possible to have other symptoms.
