Insights
Giant coronary artery aneurysms are rare in adults. This case highlights fibromuscular dysplasia as a cause of a thrombosed giant right coronary artery aneurysm presenting as an intracardiac mass after myocardial infarction.
Area of Science:
- Cardiology
- Vascular Medicine
- Pathology
Background:
- Giant coronary artery aneurysms (GCAAs) are uncommon in adults, often linked to childhood Kawasaki disease.
- Coronary artery aneurysms require prompt diagnosis and management due to potential complications like thrombosis and rupture.
Observation:
- A case of a thrombosed giant right coronary artery aneurysm was identified.
- The aneurysm presented as an intracardiac mass following an inferior wall myocardial infarction.
Findings:
- Histologic examination revealed fibromuscular dysplasia as the underlying etiology of the aneurysm.
- This finding is significant as fibromuscular dysplasia is not a commonly recognized cause of GCAAs.
Implications:
- This case expands the known etiologies of giant coronary artery aneurysms in adults.
- Highlights the importance of considering fibromuscular dysplasia in the differential diagnosis of GCAAs, even in the absence of typical Kawasaki disease history.
Abstract:
Giant coronary artery aneurysms are rare in adults and are usually found in association with Kawasaki's disease arising in childhood. We report a case of a thrombosed giant right coronary artery aneurysm presenting as an intracardiac mass detected after inferior wall myocardial infarction. Histologic analysis indicated that fibromuscular dysplasia was the underlying cause of the aneurysm.
