Neurological Sequelae After Sacral Radiofrequency Ablation: A Case of Acute Cauda Equina Syndrome.

Radiofrequency ablation (RFA) is a minimally invasive technique that uses high-frequency electrical currents to generate heat, causing controlled destruction of targeted tissues through ionic agitation. RFA-associated neuropathy is a rare but recognized complication. We present a case of cauda equina syndrome and sensorimotor neuropathy following RFA of a sacral bone metastasis. Electromyography confirmed peripheral neuropathy, particularly affecting the peroneal nerve, and MRI revealed degenerative changes and a pelvic mass near the sacrum. The patient was treated with corticosteroids and neurotrophic supplementation and subsequently discharged for oncology follow-up. This case highlights the potential for RFA-induced neuropathy, emphasizing the need for careful procedural planning, post-treatment monitoring, and further research on the role of corticosteroids in mitigating neurological complications. This finding also raises questions about the role of corticosteroids in managing such complications, emphasizing the need for personalized care and further research to improve patient outcomes.
