RESUMO
Typical cases of neuralgic amyotrophy present with sudden onset of excruciating pain in the shoulders and upper extremities, followed by marked muscle weakness and atrophy over a period of hours to days. Neuralgic amyotrophy is not confined to the brachial plexus, and difficulties in its diagnosis may delay the start of rehabilitation therapy. Here, we report a case of rehabilitation of a patient with neuralgic amyotrophy presenting with Collet-Sicard syndrome (9th, 10th, 11th, and 12th cranial nerve disorder)．A 44-year-old man developed severe pain from the left posterior neck to the occipital region, followed by sporadic onset of dysarthria, dysphagia, and difficulty in raising the left upper limb over several weeks. Nerve conduction studies showed marked bilateral differences in the amplitude of the compound muscle action potential recorded from the trapezius during accessory nerve stimulation. Needle electromyography showed abnormal resting potentials in the left trapezius and left side of the tongue and a decrease in the interference pattern during voluntary contraction. Based on the clinical course, neurological and laboratory findings, a diagnosis of neuralgic amyotrophy was made. Speech language hearing therapy was performed for dysarthria and dysphagia, and physical therapy was performed for difficulty in raising the left upper limb due to accessory nerve palsy. Rehabilitation along with recovery from inflammation-induced neuropathy allowed the patient to become independent in activities of daily living.
