Introduction:
This case describes a brachial artery mycotic aneurysm (BAMA) secondary to infective endocarditis caused by Enterococcus faecalis. BAMAs are rare and potentially limb or life threatening. A literature review revealed 61 cases since 1950, primarily caused by intravenous drug use, with Staphylococcus aureus being the most common causative bacteria.
Report:
A 71 year old man with known infective endocarditis presented with pulsatile swelling in his right antecubital fossa. A BAMA was confirmed on duplex scan. The patient underwent prompt extra-anatomic bypass with an ipsilateral cephalic vein graft.
Discussion:
Bacterial endocarditis should be acknowledged as a cause of BAMA. Prompt diagnosis and intervention are essential.
