  • Abstract
  • Look Inside

A case of 67-year-old man with inflammatory abdom-inal aortic aneurysm was reported. Two months before admission he complained of anorexia, pulsatile abdomi-nal mass, and body weight loss.

Erythrocyte sedimentation rate was 95mm/hr, and urinalysis revealed microhematuria. A CT scan demon-strated a thickened aneurysm wall which enhanced after contrast medium injection. After the diagnosis of the inflammatory abdominal aortic aneurysm was made, an operation was performed. At surgery, the aneurysm wall was found to be thickening and its elasticity had hardened. The densely adherent duode-num was not completely mobilized. A replacement of the aneurysm wall was accomplished with a bifurcated graft in the standard manner. The patient was dischar-ged without complications one month after the opera-tion. Histopathological findings showed marked col-lagen fibrosis in the adventitia, infiltration of lymphocytes and plasma cells, and germinal centers. Three months after the operation, the CT scan revealed significant regression of the wall thickening which was enhanced less than preoperatively. It is possible to make a diagnosis of an inflammatory abdominal aortic aneurysm preoperatively in the presence of typical CT findings and symptoms. Once the diagnosis is made, a graft replacement should be preferred.
