Catecholamine secreting tumors are a rare type of neuroendocrine tumors whose embryological origin is neural crest cells. 80聽% to 90聽% arise from the chromaffin cells of adrenal medulla while 10聽% to 20聽% arise from sympathetic and parasympathetic ganglia. Paragangliomas can be symptomatic due to excess catecholamine secretion or can be asymptomatic. Definitive treatment of paragangliomas is surgical resection.
