This article reports the difference between neuralgic amyotrophy and neuropathy caused by chemotherapy and radiation treatment which manifested with severe shoulder pain followed by marked weakness of bilateral upper arms and involvement of cranial nerves. A 62-year-old man presented with acute severe neuropathic pain at the left shoulder, bilateral shoulder weakness, hoarseness of voice from vocal cord palsy, and respiratory insufficiency from left diaphragm palsy, which all occurred sequentially over a 1-month period. The diagnosis of neuralgic amyotrophy was supported and differentiated from tumor-induced and radiation-induced neuropathy by clinical presentation, electrophysiologic and imaging studies. Unlike previ- ous reports of the onset of neuralgic amyotrophy being associated with initiation of radiation treatment in cancer patients, this report demonstrates that neuralgic amyotrophy can occur at any point of the malignant disease process after radiation and chemotherapy.
