However, histologic analysis of other vessels, such as the aorta, may be necessary for patients with chronic periaortitis
, including inflammatory abdominal aortic aneurysms and retroperitoneal fibrosis, which are frequently similar in patients with IgG4-related and non-IgG4-related disease (5).
and periarteritis are the most common lesions affecting various medium- to large-sized arteries, including the abdominal aorta, iliac artery, renal artery, and mesenteric artery (57).

(88,91-96) Many diseases such as Riedel thyroiditis (RT), Mikulicz syndrome, periaortitis
, multifocal fibrosclerosis, retroperitoneal fibrosis, and idiopathic membranous glomerulonephritis, described as separate entities previously, have now been categorized as part of the IgG4-RD spectrum.
