Abstract:
A patient who underwent endovascular abdominal aortic repair for a non-inflammatory abdominal aortic aneurysm developed asymptomatic periaortitis 2.5 years postoperatively. Conservative management resulted in aneurysm shrinkage and reduced inflammation. However, at 6 years postoperatively, tumor-like soft tissue shadows appeared around the aorta and the aneurysm diameter re-expanded. This was diagnosed as a recurrence and worsening. Prednisolone was initiated, leading to reductions in both aneurysm size and the mass-like shadow size. When the dosage was decreased, inflammation flared up again. The medication dose was then increased. Gradual dose reduction was subsequently attempted and treatment was successfully discontinued without recurrence.
