Occult myocardial infarction due to an unusual cause: a case report of periarteritis involving the left coronary artery.

ABSTRACT:

Background

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated condition that affects multiple organs and systems.

Case summary

A 51-year-old man with a history of occult left apex myocardial infarction diagnosed based on electrocardiographic and echocardiographic findings underwent coronary computed tomography (CT) angiography for the evaluation of coronary artery disease; the findings revealed a soft-tissue mass that surrounded the aortic root and the distal portion of the left coronary artery. The mass was considered an inflammatory lesion; high glucose uptake on positron emission tomography/CT supported this assumption. Coronary angiography revealed 80% stenosis of the distal portion of the left anterior descending artery, which corresponded with the infarc
