title: Neuralgic amyotrophy manifested by severe axillary mononeuropathy limited only to the anterior branch.
abstract: BACKGROUND
  In this study we describe a case demonstrating clinical, radiographic, electrophysiologic, and surgical evidence of a restricted but severe anterior branch axillary nerve mononeuropathy due to neuralgic amyotrophy (NA).
  
  
  METHODS
  On each diagnostic modality there was severe involvement of the anterior and lateral deltoid muscle with sparing of the posterior deltoid and teres minor muscles and cutaneous innervation to the skin overlying the lateral shoulder.
  
  
  RESULTS
  No structural etiologies were discovered during surgical exploration.
  
  
  CONCLUSIONS
  This case provides another unique manifestation of NA and augments the theory of selective fascicular vulnerability.
