Giant interaortocaval pheochromocytoma

Tumors arising from chromaffin cells, which are derived embryologically from neural crest cells, are known as pheochromocytomas or paragangliomas. These tumors in the retroperitoneum are usually located in close proximity to the aorta and inferior vena cava. Radical surgical resection is the treatment of choice for these tumors. We present a rare case of a postmenopausal woman who presented to us with a symptomatic giant retroperitoneal mass situated in the interaortocaval region that we managed with surgical resection.
