“…Although our study indicated that the degrees of enhancement on CEUS were in agreement with CT enhancement in most of the mediastinal masses, CEUS showed 2 enhanced tumors that had negative findings on CT and were finally confirmed to be lymphoma and chronic granuloma by pathologic examinations separately. It is important to note that misdiagnosis may occur when some benign mediastinal tumors are also highly vascular . In this study, 2 schwannomas appeared as richly vascularized and completely enhanced on CEUS.…”

“…5) Although contrast echocardiography has been proposed for differentially diagnosing cardiac tumors, only one case of PGL was reported with described characteristics on contrast echocardiography. 6) In their reported contrast study by Zhu, et al, the myocardium and mass were opacified simultaneously, but the mass was enhanced and visually more intense than the adjacent myocardium, indicating the mass was highly vascular. No other features were noted using contrast echocardiography, and no coronary stenosis was found using angiography.…”

Cardiac paragangliomas (PGLs) are rare neuroendocrine tumors, and data regarding the features of nonfunctioning PGLs are limited. These tumors are extensively vascularized and have high risk of hemorrhage for surgery and even biopsy. Differential diagnosis including biochemical analysis of these PGLs is important for further management. In this case report, we present the clinical, laboratory, imaging, and radionuclide presentations of a rare primary nonfunctioning cardiac PGL with a coronary aneurysm. Echocardiography initially showed a large echogenic mass in the left atrioventricular groove. The mass presented a diffuse hyperenhancement pattern with a central perfusion defect on contrast echocardiography. The tumor enclosed the left coronary artery from the coronary orifice, and an aneurysm was found in the left circumflex artery, with significantly increased flow velocity. These echocardiographic features and its susceptible location are indicative of the presence of a cardiac PGL. Although all biochemical evaluations of catecholamines from blood and urine samples were negative, positron emission tomography and scintigraphy finally confirmed the diagnosis of a primary cardiac PGL. Therefore, when imaging features are indicative of the presence of PGLs, the implementation of radionuclide imaging for final diagnosis is required even if the biochemical results are negative. Recognizing these uncommon Doppler and contrast echocardiographic characteristics is important for early diagnosing these nonfunctioning PGLs.

“…The clinical features of secreting tumors are similar to those of pheochromocytoma, including systemic hypertension, headaches, palpitations, chest pain, flushing, and sweating. 3 Cardiac paraganglioma is particularly rare, with Ϸ85 reported cases ranging from 8 to 79 years of age. 4 In our patient, this incidental finding led to the diagnosis of a succinate dehydrogenase subunit B mutation, which is associated with an increased frequency of malignant disease.…”
