A Rare Case of Clinically Isolated Aortitis in a 51-Year-Old Male with Infrarenal Aorta Involvement.

Aortitis can be broadly classified into infectious and non-infectious. Infectious causes include tuberculosis, salmonella and syphilis where as noninfectious causes include rheumatological diseases such as giant cell arteritis, Takayasu arteritis and antineutrophil cytoplasmic antibodies (ANCA) vasculitides. Clinically isolated aortitis refers to inflammation of the aorta without infectious or systemic causes. Most cases of aortitis involve the aortic root, thoracic aorta and ascending aorta. We present a rare case of clinically isolated aortitis in a 51-year-old male with infrarenal aortic involvement.
