Abstract
A large extrarenal pseudoaneurysm, originating from the arterial anastomosis of a renal allograft, occurred spontaneously 7 years after transplantation in a 29-year-old diabetic patient. Although the scintigraphic examination was diagnostic of a pseudoaneurysm, pulsed Doppler and color coded Doppler ultrasound failed to demonstrate a Doppler signal, suggesting erroneously a nonvascular fluid collection. The role of scintigraphy combined with duplex ultrasound in this rare but potentially fatal complication of renal transplantation is discussed.
