Case 16

Abstract Neuralgic amyotrophy is a relatively uncommon disorder but important to recognize since it may be confused with brachial plexopathy, cervical radiculopathy and entrapment/compressive mononeuropathies of the upper extremity. Neuralgic amyotrophy is also known as acute brachial neuritis, acute brachial plexitis, and Parsonage-Turner syndrome. This case highlights the variable clinical and electrodiagnostic findings encountered in patients with neuralgic amyotrophy, with special attention to the most common mononeuropathies affected in this disorder. This include the long thoracic nerve, axillary nerve, phrenic nerve and anterior interosseous nerve. The peculiar needle electromyography findings associated with neuralgic amyotrophy, including selective motor branch involvement, are also discussed.
