Giant Coronary Artery Aneurysm in a Patient With Castleman Disease.

ABSTRACT:

Background

Giant coronary artery aneurysms (CAAs), defined as aneurysms exceeding 20 mm, are rare vascular anomalies with potentially life-threatening complications such as thrombosis, embolization, and rupture. CCAs are typically linked to atherosclerosis and vasculitis, and their occurrence in Castleman disease (CD), a rare lymphoproliferative disorder, is exceedingly rare.

Case summary

A 68-year-old man presented with a large right atrial mass on echocardiography, later identified on coronary computed tomography angiography and cardiac magnetic resonance imaging as a giant right coronary artery aneurysm with thrombus.

Discussion

This case highlights a rare presentation of a giant CAA associated with CD and the potential role of interleukin-6 (IL-6) in aneurysm path
