Pheochromocytoma and paraganglioma: imaging characteristics
The accurate diagnosis of adult pheochromocytoma and paraganglioma necessitates a multidisciplinary approach that includes clinical history, biochemical testing, and multimodality imaging such as computed tomography, magnetic resonance imaging, and nuclear medicine studies. This review illustrates the different imaging characteristics of primary adult pheochromocytomas as well as both sympathet...
متن کاملGenetic Alterations in Pheochromocytoma and Paraganglioma
Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from neural crest-derived cells of the adrenal medulla and the extra-adrenal paraganglia. They cause hypertension due to an abnormally high production of catecholamines (mainly adrenaline and noradrenaline), with symptoms including recurrent episodes of headache, palpitations and sweating, and an increased risk of cardiov...
متن کامل15 YEARS OF PARAGANGLIOMA: Imaging and imaging-based treatment of pheochromocytoma and paraganglioma.
Although anatomic imaging to assess the precise localization of pheochromocytomas/paragangliomas (PHEOs/PGLs) is unavoidable before any surgical intervention on these tumors, functional imaging is becoming an inseparable portion of the imaging algorithm for these tumors. This review article presents applications of the most up-to-date functional imaging modalities and image-based treatment to P...
متن کاملMoving Beyond "Lumpology": PET/CT Imaging of Pheochromocytoma and Paraganglioma.
High somatostatin receptor expression on the cell membrane of succinate dehydrogenase mutation-related pheochromocytoma and paraganglioma provides a potential target for imaging and therapy. (68)Ga-DOTATATE positron emission PET/CT may represent a new gold standard for staging pheochromocytoma/paraganglioma and have future therapeutic implications.
متن کاملPheochromocytoma and Paraganglioma: Current Functional and Future Molecular Imaging
Paragangliomas are neural crest-derived tumors, arising either from chromaffin sympathetic tissue (in adrenal, abdominal, intra-pelvic, or thoracic paraganglia) or from parasympathetic tissue (in head and neck paraganglia). They have a specific cellular metabolism, with the ability to synthesize, store, and secrete catecholamines (although most head and neck paragangliomas do not secrete any ca...
