A Case of Teratoid Cyst in the Lumbar Region

One of the least frequently encountered nongliomatous intraspinal neoplasm is the teratoma. Tumors that are not dermoid or epidermoid cyst have been reported as being teratomatous or teratoid when they do not have tissue derived from all three germ layers and when they are clearly most closely related to the trigerminal teratoma. Authors described an illustrated case report of teratoid cyst of the spinal cannal, summarized the previous report cases, and discuss the classification and origin of these tumors.
