Resumen

Presentamos el caso de un varón de 69 años sin patología previa de interés que presentó clínica de pérdida de fuerza distal en miembros inferiores de dos meses de evolución. La resonancia magnética (RM) mostró la presencia de una masa intramedular a nivel del cono. El paciente fue intervenido practicándose resección de la tumoración, mostrando el estudio histológico la presencia de un carcinoma de células claras correspondiente a una sospecha de metástasis de un tumor renal, que posteriormente se confirmó con una tomografía axial computarizada (TAC) abdominal. Cuando el estado del paciente es bueno, la cirugía puede subsanar el déficit neurológico producido por la lesión intramedular. Nuestro paciente, tras la intervención, mejoró su estado neurológico; y actualmente, tras 14 meses, se mantiene sin déficit neurológico en miembros inferiores.

Summary

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 impro-ved after the intervention, and 14 months after surgery, he has no neurological deficit in the lower limbs.

Key words:
Metastasis
Intramedullary spinal cord
Renal carcinoma
