CARDIAC MRI FEATURES OF A CARDIAC PARAGANGLIOMA

Cardiac paraganglioma.

Primary Cardiac Pheochromocytoma (Paraganglioma)

Pheochromocytomas are catecholamine-producing neuroendocrine tumors arise from primitive neural crest cells. About 90% of these tumors occur as solitary benign tumors of the adrenal medulla, where majority of chromaffin cells are concentrated. Only ten percent originates from extra-adrenal sites with the organ of Zukerkandal (paraganglia along abdominal aorta) being the most common. Chromaffin ...

Multimodality imaging of a cardiac paraganglioma

Paragangliomas are rare neuroendocrine tumors arising from the ganglia of the sympathetic or parasympathetic nervous system. Less than 160 cases of intrapericardial or intracardiac paragangliomas have been reported in the English language peer-reviewed medical literature. Here, we report a case of intrapericardial paraganglioma, which illustrates some typical multimodality imaging features of t...

Black cardiac paraganglioma in a multiple paraganglioma syndrome.

We describe a unique case of a patient with a 'pigmented' cardiac paraganglioma in a multiple paraganglioma syndrome. She was symptomatic for arrhythmias, hypertensive crises and dyspnoea due to a cardiac tumour, which was richly vascularised from the right coronary artery and was partially obstructing the right atrioventricular inflow. She was operated on, but the mass was not completely resec...

Cardiac MRI

Introduction Cardiac MR imaging allows for the examination of anatomy, function, and metabolism and its clinical use is steadily increasing. It poses unique challenges to the imaging protocols as it requires high spatial resolution over a larger volume in the presence of cardiac and breathing motion. This overview of cardiac MRI discusses methods to reduce motion artifacts and various clinical ...
