An Uncommon Cause of Recurrent Dialysis Catheter-Related Bacteremia.

A 54-year-old man on maintenance hemodialysis with recurrent catheter-related bloodstream infections due to Staphylococcus aureus was admitted. Multiple prior transthoracic echocardiograms failed to reveal any vegetation. Subsequently on transesophageal echocardiography a mass consistent with fibrin sheath vegetations was identified and a follow-up diagnostic computed tomography (CT) venogram confirmed the presence of a fibrin sheath with vegetations.
