[Intramedullary spinal cord metastasis as the first manifestation of a renal carcinoma].

We present the case of a 69 year-old male without known antecedente who presented a clinical loss of distal force in his lower limbs during the last two months. Magnetic resonance imaging (MRI) showed an intramedullary spinal cord mass at the level of the medullaris cone. The patient was operated on; the histological diagnosis was clear cells carcinoma suggestive of metastasis from an unsuspected renal tumor that was later confirmed with an abdominal CT. When the patient's state is good, surgery can correct the neurological deficit produced by an intramedullary spinal cord lesion. The neurological state of our patient improved after the intervention, and 14 months after surgery, he has no neurological deficit in the lower limbs.
