Este artículo muestra la asociación entre ciatalgia y radiculopatía o plexopatía lumbosacra compresiva debida a causas extraespinales.
Presentamos un varón de 75 años con ciatalgia aguda y alteraciones motoras y sensitivas en su extremidad inferior derecha. Un gran aneurisma de aorta abdominal causa la radiculopatía. Tras tratamiento quirúrgico del aneurisma se objetiva recuperación neurológica.
Se discuten las relaciones entre aneurismas de arterias abdómino-pélvicas y los síntomas.
Las causas extraespinales de radiculopatía son raras, pero deben ser consideradas en el diagnóstico diferencial. Los estudios iconográficos raquídeos, abdominales y pélvicos son necesarios para el correcto diagnóstico.
This case is reported to remark the association between sciatic pain and lumbosacral root or plexus compression due to extraspinal causes.
We present a 75 years old male suffering from acute sciatica with motor and sensory disturbances on the right leg. A large abdominal aortic aneurysm was found to be causing lumbosacral radiculopathy. The patient had a neurological recovery after surgical treatment of the aneurysm.
The relationship between the abdomino-pelvic artery aneurysm and clinical symptoms is discussed.
Extraspinal causes of radiculopathy are rare, but they should be considered in the differential diagnosis. Imaging studies of the spinal canal, abdomen and pelvis are helpful in determining the corred diagnosis.
