CTICasesLeft Atrial Myxoma with Acute Aortic Occlusion
[...]. Left Atrial Myxoma with Acute Aortic Occlusion. CTICases. Published March 17, 2017. https://str-case-explorer.pages.dev/c/tw5z4
Imaging findings
An outside CT scan shows a large, lobulated, hypoattenuating mass within the left atrium, which was surgically confirmed to have a villous architecture and a connection to the fossa ovalis. The patient presented with acute, complete occlusion of the distal abdominal aorta due to massive tumor embolization.
Key takeaways
Cardiac myxomas are benign neoplasms but can have highly friable, gelatinous, or villous physical characteristics that predispose them to embolization. Although they commonly embolize to cerebral or peripheral arteries, they can rarely present as a sudden, catastrophic occlusion of the distal aorta.
