The many faces of IgG4-related disease: report of a case with inaugural recurrent aortic aneurism ruptures and literature review
Vascular involvement in IgG4-related disease (IgG4-RD), is a well-recognized feature and large vessel commitment, especially the aorta, can be the only manifestation of the disease. Being a newly recognized disease, its diagnosis and workup still represents a challenge in clinical practice. A 47-year-old-man with two aortic aneurysms ruptures, one at abdominal and the other at thoracic level, was referred to our rheumatology department. The initial analysis of the surgical specimen obtained 3 years earlier revealed a nonspecific aortitis. Re-evaluation of the biopsy with immunohistology now demonstrated the presence of IgG4 deposits. Evidence-based recommendations regarding diagnosis, treatment and follow-up of IgG4-related large-vessel involvement are lacking. In this particular case, histopathology were crucial. The authors review and discuss vascular involvement in IgG4-RD and respective treatment options.
