An Intradural Extramedullary Enterogenous Cyst in the Conus Medullaris: A Report of a Rare Presentation

Intraspinal enterogenous cysts are rare congenital abnormalities that mainly develop in the spinal canal, more commonly in the cervical and thoracic regions, and rarely in the lumbar spine. We present a case of neurenteric (NE) cyst in the conus medullaris and cauda equina junction at the level of L1 in a patient presenting with a nine-year history of progressive lower limb weakness, paresthesia, and muscle wasting. The patient underwent complete resection of the cyst and had no postoperative complications with marked improvement of paresthesia and some localized pain in the lower back manageable by analgesics.
