Introduction: Radiation-induced brachial plexopathy (RIBP) is a rare but severe pain syndrome, most often seen after high-dose radiotherapy for breast or thoracic malignancies. Incidence is less than 1.5% of patients[1,2]. RIBP is characterized by progressive neuropathic pain, sensory loss, and motor dysfunction often resulting in disability. Pain management is challenging as conventional strategies frequently provide limited relief. This case highlights a multimodal interventional approach to RIBP pain using ultrasound-guided interscalene nerve blocks and botulinum toxin injections.
