Mycotic aneurysm of the small bowel presenting as gastrointestinal haemorrhage

Since the advent of modern antibiotic therapy and active surgical treatment of bacterial endocarditis, septic embolization of the systemic circulation is rarely seen. An unusual presentation of a mycotic aneurysm with gastrointestinal haemorrhage in a patient with non-Hodgkin's lymphoma and aortic valvular endocarditis which had been managed by aortic valve replacement six weeks before the haemorrhage occurred is reported.
