An adult presented with left shoulder pain and difficulty raising their arm after a fall three days previously. The medical history was notable for type II diabetes mellitus, hypertension, and hyperlipidemia. A physical examination showed weakness in abduction and external rotation of the left shoulder, with no evidence of neurovascular deficit. Complete blood count and chemistry panel were unremarkable. Laboratory tests were positive for Epstein-Barr virus (EBV) and negative for human immunodeficiency virus (HIV).
