Abstract

Schwannoma is a benign, solitary, and slow growing tumor which may arise from the nerve sheath of the peripheral, sympathetic, and cranial nerves. Ancient schwannoma is a rare variant of schwannoma with atypical tumor cells with nuclear pleomorphism and hyperchromatism. It may be confused with a malignant mesenchymal tumor or schwannoma with malignant transformation. We report a case of an ancient schwannoma being adjacent to the transverse process of the fourth cervical spine.
