Teratoma in split cord malformation: an unusual association: a report of two cases with a review of the literature.

Split cord malformations (SCM) may be discovered as isolated occult spinal dysraphism or in association with various other overt developmental spinal abnormalities or lesions. However, the occurrence of SCM with intraspinal teratoma is rare. We report 2 cases of teratoma associated with SCM, of which one is intramedullary and the other extradural within meningocele, with a brief review of the literature.
