Myalgia, Obtundity and Fever in a Patient with a Prosthesis

OBJECTIVE: We describe a rare case of group G streptococcus (GGS) sepsis complicated by bacterial toxin myopathy. CASE: A 65-year-old man, with a history of infection of his shoulder prosthesis, presented with multiorgan failure and notable myalgia likely caused by toxins. The patient was treated successfully with antibiotics and prosthesis removal. CONCLUSION: This case suggests infection by GGS should be considered in a patient presenting with myalgia associated with sepsis. LEARNING POINTS: Infection by GGS should be considered in a patient presenting with myalgia associated with sepsis. The differential diagnosis in this case included a neurological condition (meningitis or atypical Guillain–Barré syndrome) and sepsis with myopathy induced by bacterial toxins. Group G streptococcus (GGS) infection in a prosthetic shoulder was successfully treated with antibiotics and prosthesis removal.
