  • Title: Intradural spinal teratoma: evidence for a dysembryogenic origin. Report of four cases.
    Author: Koen JL, McLendon RE, George TM.
    Journal: J Neurosurg; 1998 Nov; 89(5):844-51. PubMed ID: 9817426.
    Abstract:
    Intradural spinal teratoma is a rare tumor that can be associated with dysraphic defects. Although the origin of these tumors is traditionally thought to be secondary to primordial germ cells misplaced early in embryogenesis, the pathogenesis of intraspinal teratoma remains unclear. The authors present a series of patients in whom an intradural teratoma arose at the same site as a developmental spinal cord abnormality, including a split cord malformation, myelomeningocele, and lipomyelomeningocele. It is postulated that these lesions were the result of a dysembryogenic mechanism and were not neoplastic.
