Abstract

IgG4 aortitis is one of the entities seen in the spectrum of IgG4-related disease (IgG4-RD). It is characterized by serologic (elevated serum IgG4) and histologic features including a lymphoplasmacytic infiltrate with increased numbers of IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. Some studies have described a correlation between infections and IgG4 aortitis. We describe a patient with an aneurysm of the infrarenal descending abdominal aorta with features of IgG4-RD, as well as culture evidence of Streptococcus sanguis.
