Intradural spinal metastasis of renal clear cell carcinoma causing cauda equina syndrome

Summary

Metastasis of renal clear cell carcinoma to the spinal cord are quite rare. Intradural localization causing a cauda equina syndrome has been previously reported only in two cases.

The present report details the clinical, surgical and neuroradiological findings of a third case requiring emergency surgery, and presents data available from a brief review of cases reported in the literature.

From the data available in the literature, we suggest that cerebral and spinal MRI and PET imaging should be widely performed in the staging of patients treated for renal clear cell carcinoma, in order to early detect CNS involvement.
