The etiology of neuralgia amyotrophy remains unclear. Herpes zoster induced neuralgia amyotrophy has been reported in extremely rare cases. In this case report, we describe the clinical features and electrophysiologic findings in a 68-year-old patient with neuralgia amyotrophy associated with herpes zoster infection. We suggest that brachial plexus inflammation due to viral infection may be a direct cause of reversible neuralgia amyotrophy.

Neuralgic amyotrophy (NA) is an idiopathic disease characterized by muscular atrophy accompanied by neuralgia, where acute pain in the limb, mostly including the shoulders, leads to muscle weakeness and atrophy in the limb days to weeks after the onset of pain. Although its exact pathogenesis is unknown, genetic and nongenetic factors, such as infection, surgery, and trauma are suspected contributors. We report this case as we diagnosed NA of the right lower limb via enhanced MRI as well as EMG and have followed up the patient's prognosis and radiologic changes for one and a half years. In addition, the patient had been diagnosed with neuropsychiatric disorders, such as major depressive disorder and somatic symptom disorder.
