A Case Report: Multiple Schwannomas of the Spine

Neurinoma is the most common benign nerve sheath tumor originating from Schwann cells. Most benign neurinomas are single. Patients with multiple tumors can be seen in conditions such as neurofibromatosis (NF) type 2, whose typical sign is bilateral vestibular schwannomas. Some authors have described it as a form of schwannoma, which presents multiple schwannomas without associating with NF factors. Studies have recognized this condition as the third major form of NF [1, 2, 3]. We describe a case of multiple schwannomas in the spine associated with schwannomas by imaging and surgical features to clarify the characteristics of this disease.
