Abstract
Intraosseous notochordal rest is a rare intravertebral lesion of notochord origin which is presumably benign. It is usually an incidental finding in microscopic examination of vertebrectomy due to unrelated lesions or autopsy cases. Chordoma is a malignant neoplasm originating from notochord with a different clinicoradiographic presentation, prognosis, and treatment. However, the histology of intraosseous notochordal rest and chordoma is almost identical. Herein, we report cytomorphologic findings of a case of intraossous notochordal rest on touch preparation.
