title: Mycotic aneurysm of the ulnar artery.
abstract: BACKGROUND
  Mycotic aneurysm of the ulnar artery is extremely rare. We report a case of mycotic aneurysm of the ulnar artery due to subacute bacterial endocarditis (SBE) presenting with a painful pulsatile mass in hypotenar region.
  
  
  METHODS
  In a 39-year-old man, treated as a case of SBE, a painful progressive pulsatile mass appeared in the left hypotenar region. Ultrasonography and angiography showed an aneurysm of ulnar artery in this region. The aneurysm was resected by surgery.
  
  
  CONCLUSIONS
  Since the diagnosis may be difficult at the early phase and in some cases limb loss may occur, there should be high clinical suspicion to make a prompt diagnosis.
