Intradural extramedullary spinal metastasis is rare, representing 6% of all spinal metastasis. Indeed, intradural metastasis from a Renal Cell Carcinoma to the cauda equina is extremely rare with only 11 case reports present in the past. We present a patient with Cauda equina syndrome with an intradural extramedullary lesion causing compression of the nerve roots. He was subjected to a surgical decompression of the cauda equina with excision of the mass. The pathological examination displayed metastatic clear cell RCC with infiltration of the cauda equina. Thus, metastatic tumors constitute an important differential diagnosis for all lesions of the spine irrespective of level or location.

Keywords: Metastatic, Renal cell carcinoma, Intradural, Extramedullary, Cauda equina.
