Isolated lumbar intradural extra medullary spinal cysticercosis simulating tarlov cyst.

Spinal cysticercosis is a very uncommon manifestation of neurocysticercosis, which is caused by the larvae of Taenia solium. Here, we present a rare case of isolated lumbar intradural extramedullary neurocysticercosis, initially thought to be Tarlov cyst. A 40-year-old man, presented with low backache for 1-year with radiation of pain to right leg for 3 months. The patient was treated successfully with the surgical removal of the cyst, followed by medical treatment. Spinal neurocysticercosis should be considered in the differential diagnosis in high-risk populations, with new symptoms suggestive of a spinal mass lesion.
