<unk>  is a neuroendocrine tumor of the medulla of the adrenal glands and extra-adrenal chromaffin tissue, which fail to involute after birth, they secrete excessive amounts of catecholamines, usually epinephrine and norepinephrine. Extra-adrenal paragangliomas (often described as extra-adrenal<unk> s) are closely related, though less common.<unk>  originates from the chromaffin cells of the sympathetic nervous system ganglia and is named based upon the primary anatomical site of origin. The incidence of<unk>  ranges from a low of 0.2 per 100,000 persons to a high of 0.8 per 100,000 persons. The average age at diagnosis is 24.9 years in hereditary cases and 43.9 years in sporadic cases with men and women are equally affected. MRI and CT scan are used for the diagnosis of<unk> . Surgery is the mainstay of the treatment.
