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.

IgG4 相关性主动脉炎是 IgG4 相关疾病（IgG4-RD）谱系中的一种疾病。其特征包括血清学表现（血清 IgG4 升高）以及组织学特征，如淋巴细胞和浆细胞浸润伴 IgG4 阳性浆细胞数量增加、席纹状纤维化和闭塞性静脉炎。一些研究描述了感染与 IgG4 相关性主动脉炎之间的关联。我们报告一例患有肾下腹主动脉降段动脉瘤且具有 IgG4-RD 特征的患者，同时有血链球菌感染的培养证据。[全文可在 http://rimed.org/rimedicaljournal-2017-04.asp 获取]
