A 77‐year‐old man, with a history of lymphoma, presented with isolated neck extensor weakness and a 2‐year history of bilateral carpal tunnel syndrome (CTS). Needle electromyography showed myopathic changes, and biopsy of cervical paraspinal muscles showed amyloid deposition in blood vessels. Amyloidosis should be considered in the differential diagnosis of dropped head syndrome. Muscle Nerve, 2011
