CTICasesIntrapericardial Paraganglioma
Imaging findings
CT angiography shows a highly vascular, lobulated, centrally necrotic mediastinal mass located beneath the visceral pericardium, intimately involving the aortic root, left main coronary artery, and right ventricular outflow tract (RVOT).
Key takeaways
Intrapericardial paragangliomas (chemodectomas) are rare, highly vascular neuroendocrine tumors arising from paraganglia along the aortic root or pulmonary artery. They demonstrate intense contrast enhancement and present surgical challenges due to their intimate association with the coronary arteries and outflow tracts, requiring complex reconstruction.
