MELAS Syndrome with Cardiac Involvement: A Multimodality Imaging Approach

MELAS Syndrome with Cardiac Involvement: A Multimodality Imaging Approach

A 49-year-old man presented with chest pain, dyspnea, and lactic acidosis. Left ventricular hypertrophy and myocardial fibrosis were detected. The sequencing of mitochondrial genome (mtDNA) revealed the presence of A to G mtDNA point mutation at position 3243 (m.3243A>G) in tRNALeu(UUR) gene. Diagnosis of cardiac involvement in a patient with Mitochondrial Encephalomyopathy, Lactic Acidosis, an...

multimodality imaging of a cardiac angiosarcoma

introduction while primary malignant tumors of the heart are rare, angiosarcomas are the most common cardiac malignant tumors. case presentation we describe a 23-year-old woman who presented with a right atrial mass, which was discovered to be a cardiac angiosarcoma. we demonstrate the use of several noninvasive imaging modalities along with pathology confirmation for the definitive and compreh...

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...
