Enterogenous cysts account for 0.7-1.3% of spinal axis tumors. Cervical and thoracic segments are most often affected and they are rare in the lumbar region. Intramedullary variant which comprises less than 5% of enterogenous cysts are densely adherent to the surrounding tissue and preclude total excision. Partial excision is associated with recurrence and is the most common unfavorable outcome in these cysts. Hence, such patients need follow-up with serial imaging. We describe a case of conus medullaris enterogenous cyst presenting as lower limb pain. Due to dense adhesion of the cyst to the surrounding neural tissue, subtotal excision was done. The patient is symptom and tumor free at one year interval. We describe our case, discuss its uniqueness and review the literature on this rare but difficult to cure tumor.
