Parsonage-Turner Syndrome in the Pediatric Population: A Case Report

Parsonage-Turner syndrome, a condition rarely seen in the pediatric population, is the focus of our case report.We present the unique case of a 4-year-old boy who developed a painful right brachial plexopathy following a febrile illness.The pain was exacerbated by touch or pressure and subsided when the shoulder was left undisturbed.On examination, he exhibited significant weakness in the right shoulder, with less pronounced weakness in the right hand.Brain and cervical spine magnetic resonance imaging (MRI) were unremarkable, but a MRI of the right brachial plexus revealed nerve root thickening and signal changes in the adjacent muscles, consistent with brachial neuritis.The patient began oral steroids and was referred to outpatient neurology for follow-up.Over several weeks his pain improved, though weakness persisted.
