Schwannoma, also known as neuroma or neurilemoma, is a type of benign tumor that affects Schwann cells located in the central or peripheral nervous system.This tumor usually appears after age 50, and may appear on the head, knee, thigh or retroperitoneal area, for example.
Treatment involves surgical removal of the tumor, but in some cases this may not be possible due to its location.
- The symptoms caused by the tumor depend on the affected area.
- If the tumor is located on the acoustic nerve it can cause progressive deafness.
- Dizziness.
- Vertigo.
- Loss of balance.
- Ataxia and ear pain.
- If there is compression of the tri-in the twin nerve.
- Intense pain can occur during speech.
- Food.
- Drinking and numbness or facial paralysis.
Tumors that compress the spinal cord can cause weakness, digestive problems, and difficulty controlling pockets and limbs can cause pain, weakness, and tingling.
To make the diagnosis, your doctor should evaluate your signs and symptoms, medical history, and perform the necessary tests, such as MRI, CT scan, electromyography, or biopsy, know what a biopsy is and what it’s for.
The cause of schwannome is thought to be genetic and related to neurofibromatosis type 2, and radiation exposure may be another possible cause.
For the treatment of schwannome, surgery is generally recommended for removal, but depending on its location, the tumor may be inoperable.
