Abstract:
An asymptomatic dissecting superior mesenteric artery (SMA) aneurysm in granulomatosis with polyangiitis (GPA), historically termed Wegener's granulomatosis, is rare. We herein describe a 68-year-old man who was diagnosed with GPA based on a high level of proteinase 3 (PR3)-antineutrophil cytoplasmic antibody (ANCA). One year after remission of GPA, the patient developed pyelonephritis, and his PR3-ANCA level increased again. Computed tomography showed a rapid increase in the size of the dissecting SMA aneurysm. The patient underwent successful endovascular stent-graft repair. At the time of this writing, 3 years had passed since the surgery and the clinical course was good.
