CTICasesMediastinal/Intrapericardial Hemangioma
Imaging findings
A stable, well-circumscribed anterior mediastinal mass initially suspected to be a thymoma. MRI demonstrated T2-hyperintensity and T1-hypointensity with nodular delayed enhancement on perfusion imaging, consistent with a vascular malformation.
Key takeaways
This mass was deemed intrapericardial, explaining why it was left during initial surgical exploration. It highlights the utility of MRI/perfusion imaging in distinguishing vascular lesions from pericardial cysts or thymic remnants.
