Intramedullary mature teratoma of the conus medullaris

Teratoma is a tumor that derivatives from all three primitive germ layers and spinal intramedullary teratomas are very rare lesions. The primary treatment modality for these tumors is surgical resection, and total resection should be the aim. However, subtotal resection is a valid alternative to prevent traumatizing adjacent functional neural tissue. In this report, we presented a case of a 12-year-old male patient with spinal teratoma of the conus medullaris. We describe the presentation, evaluation, and treatment of this rare disease.
