ABSTRACT
La neuralgia amiotrófica es una neuropatía infrecuente caracterizada por la aparición de un dolor intenso unilateral en el hombro. Es rara la afectación aislada o concomitante de otros nervios motores periféricos derivados del plexo cervicobraquial, como el nervio frénico o el laríngeo. Su etiología es desconocida, aunque se han planteado varios factores que pueden condicionar su aparición. La afectación del nervio frénico, unilateral o bilateral, es aún más infrecuente. El diagnóstico se basa en la historia clínica, la exploración funcional, técnicas de imagen y en los hallazgos del electromiograma. Presentamos el caso de una mujer de 48 años con antecedentes de trasplante renal por glomerulonefritis proliferativa y rechazo posterior del mismo, que fue definitivamente diagnosticada de neuralgia amiotrófica con afectación frénica bilateral, que precisó ventilación mecánica no invasiva de forma prolongada (AU)
Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual. Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation (AU)

Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual(1). Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation.
