An exceptional case of lumbar neurenteric cyst revealed by Conus medullaris syndrome: case report with literature review

Abstract Introduction A neurenteric cyst is a rare, benign congenital spinal malformation that is classified as a type of notochordal dysraphism and categorized by the World Health Organization as ‘rare benign developmental, malformative lesions of the Central nervous system’.
