Definition:A paraganglioma (previously refered to as chemodectoma) located in the retroperitoneal space. Paragangliomas (also known as extra-adrenal pheochromocytomas) are rare tumors that arise from extra-adrenal chromaffin cells. Paragangliomas are characterized by secretions of excessive catecholamines, including epinephrine, norepinephrine and dopamine, which may lead to clinical symptoms, including episodic hypertension, tachycardia and diaphoresis. However, between 40 and 50% of paragangliomas are non-functional.
Comment:The retroperitoneum is an anatomical space located behind the abdominal or peritoneal cavity. Abdominal organs that are not suspended by the mesentery and lie between the abdominal wall and parietal peritoneum are said to lie within the retroperitoneum. Several individual spaces make up the retroperitoneum. These spaces are the anterior pararenal space, posterior pararenal space, and the perirenal space.
