We present the case of a 64-year-old woman with gluteal pain and bilateral posterolateral irradiation of a year of evolution associated with neuropathic symptoms. Despite pharmacological treatment the pain persisted and she was referred to the pain unit. Magnetic resonance imaging showed L5-S1 disc protrusion and sacral Tarlov cysts and electromyogram showed chronic radiculopathy of S1. Sacral cysts at the level of S2-S3 were considered an incidental finding and were ruled out as a cause of pain. The case was diagnosed as lumbosciatica secondary to L5-S1 disc protrusion and a transforaminal infiltration of the right S1 root was chosen, thus avoiding the possible puncture of the cysts through a caudal approach. One month later, the patient reported improvement in pain. This case highlights the importance of including Tarlov cysts in the differential diagnosis and the choice of appropriate interventional techniques, taking into account the risks associated with the presence of these cysts.
