Transarterial embolization and doxorubicin eluting beads-transarterial chemoembolization (DEB-TACE) of malignant extra-adrenal pheochromocytoma

摘要

Extra-adrenal pheochromocytomas (EAPs) are neuroendo-crine tumors that arise from paraganglion cells of the sympathetic component of the autonomic nervous system. The paraganglia are chromaffm tissue complexes that extend along the paravertebral axis . As part of the autonomic nervous system, these paraganglia are the dominant source of catecholamine production during early childhood . Failure of involution of these paraganglia leads to the development of extra-adrenal pheochromocytomas.
