Primary Retroperitoneal Inter-aorto-Caval Paraganglioma of the Organ of Zuckerkandl.

Tumour that arise from chromaffin cells at extra-adrenal locations are termed paragangliomas which are rare tumour. The organ of Zuckerkandl located along aortic bifurcation is the most common site of their occurrence. Herein, we report a case of 20-year-old male with large abdomino-pelvic paraganglioma of the organ of zuckerkandl with multiple pedicles to abdominal aorta. On exploratory laparotomy it revealed a large retroperitoneal mass with variable consistency with surfaces covered with tortuous vessels. This mass was adhered to the retroperitoneum with multiple arterial pedicles to abdominal aorta. Histopathologic evaluation revealed features of extra-adrenal paraganglioma with characteristic Zellballen appearance. Postoperative course was uneventful.
