Inflammatory aortic aneurysm: a case report and review of literatures.

ABSTRACT

A case of an uncommon variant of aortic aneurysm, inflammatory type, is reported. A 51-year-old Thai male presented with a pulsatile abdominal mass associated with pain. Ultrasonography demonstrated infrarenal abdominal aortic aneurysm preoperatively and operative findings revealed dense fibrous tissue around the lesion. Serological tests for syphilis and bacteriological studies of aneurysm contents were all negative. Aneurysmorrhaphy was done, using Dacron straight graft, and two serious complications developed at six and two months interval aortocolonic and aortoduodenal fistulae. However, the patient survived the three operations. Definite diagnosis of inflammatory aortic aneurysm was confirmed by typical pathological findings. Clinical presentations, operative and pathological findings were compared to previous literature.
