Inter-aorta-caval located tumor: a case report.

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.
