Radial artery pseudoaneurysms are rare, and those that become infected are
rarer still. We present the case of a patient who developed a radial artery
pseudoaneurysm as a late complication of arterial catheterization. Blood c
ultures were positive for Staphylococcus aureus, and a pulsatile mass, with
associated tissue necrosis, was palpable over the radial artery. The diagn
osis was confirmed by gray-scale and color Doppler sonography, which showed
a partially thrombosed pseudoaneurysm and turbulent flow in the pseudoaneu
rysm and native artery. (C) 2000 John Wiley & Sons, Inc. J Clin Ultrasound
