What is the Neurofibroma Of The Brain?Neurofibroma of the brain is a rare benign (non-cancerous) tumor of the cells of the myelin sheath of peripheral nerves. These are Schwann cells, fibroblasts, and perineural cells of the myelin sheath; this sheath surrounds supports, and protects the peripheral nerves of the brain and spinal cord. These tumors invade the nerve and destroy its sheath and fibers. The most commonly affected nerve is the vestibulocochlear nerve, which is responsible for hearing and balancing the body.
What are the Peripheral Nerves Of The Brain And Spinal Cord?Peripheral nerves are 43 pairs of nerves that connect the brain and spinal cord to the entire human body. These nerves perform various functions of sensation, movement, and muscle coordination.
Disease Etiology (Causes)There is no well-known cause; certain genetic mutations are responsible for the development of neurofibroma. A genetic disorder called von Recklinghausen causes multiple nerve damage due to neurofibroma.
Signs and SymptomsSigns and symptoms depend on the location and size of the affected nerve. These are usually non-cancerous and very slow-growing tumors, which in most cases remain asymptomatic.
DiagnosisThe following diagnostic tests and procedures can be used to make a diagnosis. These are
- Imaging tests such as X-Ray, CT-scan (computerized tomography), PET-scan (Positron emission tomography) help detect the site, size, and location of the tumor.
- Tumor biopsy and histopathological examination
