Inter-aorta-caval Located Tumor: A Case Report

Abstract

A paraganglioma is a rare tumor that develops out of extra-adrenal chromaffin cells and pheochromocytomas originating from the adrenal medulla. Early diagnosis and surgical planning are crucial, since the tumor secretes catecholamine and is adjacent to large vessels in the abdomen. Furthermore, since complete resection improves the prognosis, we recommend a meticulous surgical technique. Here, we present a case of paraganglioma in a 32-year-old male patient who initially presented with a stomachache. After conducting the required tests, we resected the tumor that was pressing against the vena cava in the interaortocaval region.

Intraoperative diagnosis of functional retroperitoneal multiple paraganglioma: A case report

“…Of these tumors, 85% are located in the abdomen, usually in the perinephric and paraaortic spaces. They do not usually invade between the abdominal aorta and inferior vena cava (9). The incidence of multicentricity of paragangliomas has been reported as 15-24% in the literature (10).…”

Laparoscopic resection of a paraganglioma located on the border of the thoracic and abdominal cavities using a transabdominal‐transdiaphragmatic approach

“…A paraganglioma is a tumor originating from a paraganglion of the sympathetic or parasympathetic nervous system. Tumors are often in contact with the aorta or inferior vena cava, rendering removal difficult . Because tumors are associated with abnormal levels of catecholamine secretion, care is required during removal .…”
