Congenital Elongated Lumbar Dermoid Cyst Combined with Sacral Meningocele

ABSTRACT

Dermoid cysts of the spinal canal are rare benign congenital tumors, accounting for 1~2% of all intraspinal tumors. We report a case of lumbar extramedullary cyst, combined with congenital sacral meningocele. The clinical features, characteristics on MRI, pathologic findings, and surgical treatment of such a rare extramedullary benign tumor is discussed with the relevant literature.
