Spinal schwannoma


Spinal schwannomas are benign nerve sheath tumors that occur within the spinal canal and are composed primarily of Schwann cells of spinal nerve roots 1-6. When they are intraspinal and extend for two or more vertebral segments, they are called giant intraspinal schwannomas 4,5.

This case illustrates the MRI findings of a giant intraspinal lumbar schwannoma, align with the long axis of the cord, forming a sausage-shaped mass, extending over several levels, and with posterior scalloping of the vertebral body. This is a case of a pathology-proven schwannoma with the typical histologic features of Antoni type A and Antoni type B areas.
