    Abstract:
    A 63-year-old man who had undergone aortoiliac bypass with an expanded polytetrafluoroethylene (PTFE) graft was referred to our hospital for investigation and treatment of a possible pseudoaneurysm of the abdominal aorta. A tender, pulsatile, and bulging mass, about the size of an adult fist, was palpated around the navel. Enhanced computed tomography (CT) showed a large low-density area around the abdominal aorta and PTFE graft, and aortography showed a patent graft with no anastomotic leakage. Operative inspection revealed that the pulsatile mass was a large perigraft seroma, and we replaced the PTFE graft with a new woven Dacron graft. The patient has been well with no sign of recurrence for 1 year, although close long-term follow-up is mandatory.
