Cardiac CT Appearances

Cardiac Angiosarcoma CT Findings

Highly aggressive tumors consisting of irregularly shaped vascular channels lined by anaplastic epithelial cells with sizable areas of necrosis and hemorrhage.
They are of right atrial origin in approximately 75% of cases and typically fill this chamber and then infiltrate into the pericardium, tricuspid valve, right ventricle, and right coronary artery .
Metastases develop in 47% to 89% of patients, most commonly to the lungs but also to the bone, colon, and brain.
