Endocarditis is a recognised complication ofhemodialysis. This is generally only thought of in terms of infective vegetations. We present a case of right-sided NBTE in a patient with an indwelling venous catheter who also had advanced pelvic malignancy. The unusual side of this patient's endocarditic lesions implicates a role for the venous catheter in determining the site of non-bacterial thrombus formation. It is also a reminder that endocarditis is always a risk when using central venous catheters, even after appropriate sterile precautions have been taken.
