Superior mediastinal paraganglioma associated with von Hippel-Lindau syndrome: report of a case
Extra-adrenal pheochromocytomas are termed paragangliomas. Paragangliomas in the mediastinum, especially the superior mediastinum, are extremely rare. It is known that paragangliomas or pheochromocytomas occur in combination with von Hippel-Lindau syndrome. We present the case of a non-functional superior mediastinal paraganglioma in a patient with von Hippel-Lindau syndrome, without a familial...
متن کاملMagnetic resonance imaging of mediastinal paraganglioma.
The magnetic resonance (MR) findings are presented of a nonfunctioning mediastinal paraganglioma on both T1- and T2-weighted magnetic resonance images. The MR characteristics of this tumor differentiate it from previously reported functioning mediastinal paragangliomas (pheochromocytoma) and from other benign mediastinal neoplasms, although mediastinal bronchogenic carcinoma may produce a simil...
متن کاملMediastinal paragangliomas: association with mutations in the succinate dehydrogenase genes and aggressive behavior.
Extra-adrenal pheochromocytomas, otherwise known as paragangliomas (PGLs), account for about 20% of catecholamine-producing tumors. Catecholamine excess and mutations in the genes encoding succinate dehydrogenase subunits (SDHx) are frequently found in patients with PGLs. Only 2% of PGLs are found in the mediastinum, and little is known about genetic alterations in patients with mediastinal PGL...
متن کاملParagangliomas/Pheochromocytomas: Clinically Oriented Genetic Testing
Paragangliomas are rare neuroendocrine tumors that arise in the sympathetic or parasympathetic nervous system. Sympathetic paragangliomas are mainly found in the adrenal medulla (designated pheochromocytomas) but may also have a thoracic, abdominal, or pelvic localization. Parasympathetic paragangliomas are generally located at the head or neck. Knowledge concerning the familial forms of paraga...
متن کاملPulmonary Paraganglioma Manifesting as an Endobronchial Mass
Thoracic paragangliomas comprise only 1-2% of all paragangliomas, including the adrenal pheochromocytomas, and these tumors are mostly found in the mediastinal compartments (1). To the best of our knowledge, there is only one case report in the pathology literature of endobronchial involvement by a primary pulmonary paraganglioma (2). We report here on the CT and bronchoscopic findings of a cas...
