ABSTRACT

Parsonage-Turner syndrome is an unusual neuromuscular disorder of unknown etiology that can be confused with other causes of pain or weakness, of the shoulder and arm. It is important to distinguish this disorder because of its dramatic symptoms and relatively good prognosis. Sharp shoulder pain, marks the onset of brachial neuritis, but is relatively short-lived. Weakness generally occurs as the pain is subsiding and most frequently involves muscles innervated by the supraescapular, less frequently the axilar nerve and rarely the musculocutaneous nerve. Electromyography shows if the lesion is bilateral, and also is of both diagnostic and prognostic value. Other laboratory studies serve only to exclude other causes of shoulder pain. The clinical course is variable, but in 90 per cent of patients complete recovery occurs within three years. We present a case of brachial neuritis with a discussion of the main imaging findings using MRI and a brief review of the literature.
