Abstract

Most of intradural tumors are primary tumors and few of them are metastatic tumors. Especially, spinal intradural metastatic tumors which are derived from renal cell carcinoma are rarer. Even though such tumors occur, it accompany with brain metastasis in many cases. And there was no report regarding isolated intradural metastasis, without metastasizing on brain or other central nervous system organs, in domestic.

The purpose of this research is to report the excellent clinical results regarding solitarily intradural metastasized renal cell carcinoma. Researchers found out renal cell carcinoma which was solitarily metastasized intradural of the third lumbar of 63 years old man who has renal cell carcinoma and underwent nephrectomy 2 years before. tumor extirpation was performed after total laminectomy. And after keeping watching it for 2 years, we could get favorable results and would like to report it with review of literature.

Keywords: Intradural metastasis, Renal cell carcinoma

Fig. 1.

MRI images indicate an intradural extramedullary mass at L3. (A) T1-weighted MRI image shows hyperintensity relative to the surrounding spinal fluid. (B) T2-weighted MRI image shows low signal intensity. (C) Homogeneous enhancement of the mass was demonstrated in gadolinium enhance image.

Fig. 2.

H-E stained sections of the spinal metastasis show a tumor identical in appearnces to renal cell carcinoma (origingal magnification, ×400).
