A strange case of dyspnoea

Acquired neuralgic amyotrophy, described for the first time by Parsonage and Turner, is a rare idiopathic disease that may occur in otherwise normal healthy individuals. It typically begins with sudden, unilateral shoulder pain that may also involve the neck and/or arm. Less frequently, the disease involves nerves other than those of the brachial plexus, such as phrenic nerves, resulting in dyspnoea. The diagnosis is based on the clinical presentation and is generally supported by electroneurography/electromyography. We report the case of a 45-year-old white man who was referred to our clinic for acute dyspnoea preceded by severe neck and right shoulder pain. Corticosteroid therapy ameliorated the clinical picture, but without a complete recovery.
