ABSTRACT Introduction 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. Muscle Nerve 52 : 143–145, 2015
