ABSTRACT

Las funciones o disfunciones de las vías del dolor periféricas y centrales pueden originar un cuadro álgico distinto al nociceptivo, mucho menos frecuente pero igualmente importante, que se describe como dolor neuropático. Este dolor neuropático no es una enfermedad propiamente dicha, es una manifestación de múltiples y variados trastornos que afectan al sistema nervioso central y a sus componentes somatosensitivos. El dolor neuropático puede aparecer en trastornos del sistema nervioso central y, especialmente, en lesiones medulares, esclerosis múltiple y lesiones cerebrovasculares del tronco del encéfalo y el tálamo. El dolor neuropático, que se origina en lesiones del sistema nervioso central, no suele responder a la estimulación medular. Se presenta el caso de un paciente que padece una lesión tumoral dorsal (hemangioma) a nivel torácico con paraparecia espástica secundaria y dolor neuropático no controlado de 7 meses de evolución, al cual se le instala un sistema de neuromodulación, que logra controlar el dolor y la recuperación del paciente.


Lesions or malfunctions of peripheric and central pain pathways may cause algid clinical manifestations, and despite being much less frequent, are equally important. These are described as neuropathics pain. This neuropathic pain is not in itself a disease, but a manifestationof multiple and varied disorders that affect the central nervous system and its somatosensitive components. Neuropathic pain may be associated to disorders of the central nervous system and specially in bone marrow lesions, multiplesclerosis, and brain vascular lesions of the brain trunk and thalamus. Neuropathic pain that results from damages of the central nervous system does not usually respond to bone marrow stimulation. This is the case of a patient with a dorsal tumour lesion (hemangioma) at thoracic level with secondary spastic parapareis and uncontrolled neuropathic pain present for a period of 7 months to which a neuromodulation system is installed in order to control pain and recover the patient, finally accomplishing the two objectives.
