Radiation-induced arteritis of large vessels and brachial plexus neuropathy are uncommon delayed complications of local radiation therapy. We describe a 66-year-old woman with right arm discomfort, weakness, and acrocyanosis that developed 21 years after local radiation for breast adenocarcinoma. Arteriography revealed arteritis, with ulcerated plaque formation at the subclavian-axillary artery junction, consistent with radiation-induced disease, and diffuse irregularity of the axillary artery. Electromyography showed a chronic brachial plexopathy. The patient's acrocyanosis, thought to be due to digital embolization from her vascular disease, improved with antiplatelet therapy. The concurrent combination of radiation-induced arteritis and brachial plexopathy is uncommon but should be considered in patients presenting with upper extremity pain or weakness after radiation therapy.
