CTICasesIntimal Sarcoma
Imaging findings
A large cardiac mass was observed in the left atrium, which initially mimicked a myxoma. Key features included involvement across both the interatrial septum and the roof of the atrium, as well as extension to the right atrial side of the septum.
Key takeaways
Intimal sarcomas are important mimics of cardiac myxomas. Extension across the interatrial septum and involvement of the right atrial side are red flags that should raise suspicion for a malignant process like intimal sarcoma.
