[neuralgic amyotrophy]

Neuralgic amyotrophy is considered to be a form of mononeuropathy multiplex which generally involves the nerves of the upper limbs.We describe four cases of neuralgic amyotrophy revealed by dyspnea due to phrenic nerve involvement, with asymptomatic motor deficit in the upper part of the brachial plexus.Phrenic nerve involvement revealed by dyspnea is rare. Associated with neurologic signs, the diagnosis is evocative. In case of an isolated attack, the key to diagnosis is the electromyographic exam.
