Plasmacytic Aortitis with Occlusion of the Right Coronary Artery

Patient: Male, 55 Final Diagnosis: Plasmacytic aortitis Symptoms: Dizziness • nausea Medication: — Clinical Procedure: — Specialty: Surgery OBJECTIVE: Unusual clinical course BACKGROUND: Inflammation of the aortic wall, known as aortitis, is a rare clinical entity which is frequently asymptomatic, or identified when the patient presents with an aortic aneurysm or dissection. It is most often caused by infection or autoimmune vasculitides such as giant cell or Takayasu’s arteritis. CASE REPORT: The case presented is that of a 55-year-old man with symptomatic occlusion of the right coronary artery caused by a plasmacytic aortitis suggestive of IgG4 disease, which was successfully treated with coronary artery bypass grafting and an ascending aortic graft. CONCLUSIONS: A review of the current literature emphasizes how poorly the etiology and natural history of plasmacytic aortitis is understood.
