RESUMEN
We report the case of a 56 year old cirrhotic woman who presented during the course of a tuberculous spondylodiscitis affecting T9-T10, a clinical picture consistent with neuralgic amyotrophy affecting the right shoulder first, and later also the left one (Parsonage-Turner syndrome). This is an uncommonly diagnosed entity of unknown etiology and pathogenesis. Magnetic resonance images (MRI) include high signal intensity in supra and infraspinatus muscles and other muscles of the shoulder girdle, compatible with muscle oedema associated with denervation. These features, combined with the ability of MRI to exclude local problems as tendinitis stresses the importance of this technique in the diagnostic evaluation of patients with neuralgic amyotrophy.
