Ascending aortic aneurysm associated with lymphoplasmacytic thoracic aortitis mimics acute type A intramural hematoma - case report.

INTRODUCTION

Lymphoplasmacytic thoracic aortitis is still underrecognized cause of thoracic aortic aneurysm.

CASE REPORT

We herein report a case of symptomatic inflammatory ascending aortic aneurysm and pericarditis diagnosed on CT scan as acute type A intramural hematoma. Patient underwent emergency supracoronary ascending aorta replacement with a prosthetic graft. Marked inflammatory thickening of aneurysm wall was the intraoperative finding. Histopathologic examination of the excised aortic tissue showed inflammation with lymphoplasmacytic pattern of aortitis.

CONCLUSION

This case demonstrates that lymphoplasmacytic aortitis may mimic symptoms and radiological findings of intramural hematoma.
