    "definition": "Non-functioning paraganglioma is a rare neuroendocrine tumor arising from neural crest-derived paraganglion cells (most often in the para-aortic region at the level of renal hilia, organ of Zuckerkandl, thoracic paraspinal region, bladder, and carotid body) not associated with catecholamine secretion. These tumors are usually clinically silent and symptoms, if present, are nonspecific and depend on the location of the tumor. Association with certain hereditary cancer-predisposing syndromes, such as multiple endocrine neoplasia, neurofibromatosis type 1 or von Hippel Lindau syndrome, may be observed."

Infrequently, it may arise outside the usual distribution of the sympathetic and parasympathetic paraganglia. Tumors arising from the adrenal gland medulla are called pheochromocytomas. Morphologically, paragangliomas usually display a nesting (Zellballen) growth pattern. There are no reliable morphologic criteria to distinguish between benign and malignant paragangliomas. The only definitive indicator of malignancy is the presence of regional or distant metastases."
