Imaging findings
Subtle rims of low attenuation in both ventricles on CT, with thick walls. MRI shows typical thrombus in both ventricles and delayed subendocardial enhancement of both ventricles, while still preserving motion of all LV segments.
Key takeaways
The patient presented with heart failure and eosinophilia. Eosinophils degranulate, creating a prothrombotic environment in the subendocardium, associated with enhancement and thrombus formation. Biopsy confirmed the diagnosis. It's crucial to differentiate this from thrombus due to stagnant flow (e.g., in a left ventricular aneurysm) by observing preserved LV segment motion.
