Split cord malformation and cystic teratoma masquerading as lipomeningomyelocele.

INTRODUCTION. Split cord malformations are commonly associated with other tethering lesions such as short, thick filum terminale and intraspinal lipomas. However, the occurrence of split cord malformation with teratoma is rare. Only 16 such cases have been reported in the English literature. CASE REPORT. A case of split cord malformation with teratoma masquerading as lipomeningomyelocele is reported, and the possible embryogenesis of this lesion is discussed.
