A 53-year-old woman with end-stage renal impairment on hemodialysis was evaluated for recurrent episodes of Corynebacterium jeikeium bacteremia and endocarditis. Her recurrences occurred despite surgical debridement and extended courses of culture-directed antimicrobial therapy. The clinical course was complicated by the requirement of various endovascular prostheses for vascular access. To our knowledge this degree of relapse with guideline medical and surgical therapy is rare and challenges current practice and understanding of this group of infection.
