ABSTRACT:

Background

Immunoglobulin G4 (IgG4)-related diseases are systemic fibroinflammatory disease characterized by extensive infiltration of IgG4-positive plasma cells in the affected tissue(s), with high plasma levels of IgG4. However, coronary involvement is rare.

Case summary

A 70-year-old man was diagnosed with IgG4-related coronary arteritis, pancreatitis, and cholangitis during full-body contrast computed tomography (CT) examination prior to surgery for an iliac artery aneurysm. ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/CT showed increased uptake of ¹⁸F-FDG in the pancreas, extrahepatic bile ducts, and proximal right coronary artery (RCA).
