Abstract
The aim of this case report is to inform clinicians about radiation-induced brachial plexopathy, a rare complication that often presents well after treatment with inconsistent symptoms and manifestations. It is often a diagnosis of exclusion when a neoplastic or other cause cannot be identified. Electrodiagnostic testing is particularly useful. Here, the results of a standardized grip and pinch strength assessment and dexterity test are presented in a woman whose symptoms first appeared 20 years after completing treatments for stage IIIA breast cancer.
