We report a case of a 33-year-old female patient who presented a large firm retroperitoneal tumor situated on the left flank above the left kidney. Levels of the serum epinephrine and norepinephrine were high. We performed a scanned biopsy; the histopathological examination and the immunohistochemical analyses concluded the diagnosis of a retroperitoneal paraganglioma. The tumor was judged secreting and inoperable; therefore it was decided to be treated with radiotherapy. <br /> </p>}, number={1}, publisher={Selçuk BAŞAK}
