Sporadic schwannomas and neurofibromas
Sporadic schwannomas and neurofibromas are benign tumors that arise from the nerve sheaths of cranial nerves, nerve roots, spinal nerves, and peripheral nerves. Most schwannomas originate from the eighth cranial nerve, whereas neurofibromas more commonly arise along the spinal nerve roots and can occur in superficial (cutaneous, subcutaneous) and deep (visceral, spinal, orbital) locations. When intervention is indicated, surgical resection is the treatment of choice.
