Abstract
Paragangliomas are rare neoplasms arising from cells of the primitive neural crest. These tumours are often difficult to diagnose and treat. We report a case of a 42 year old female presenting with abdominal pain who had a retroperitoneal tumour situated at the aortic bifurcation. Serum catecholamine levels were normal. Complete resection of the tumour was performed. The histological examination and immunohistochemical analyses concluded the diagnosis of an organ of Zuckerkandl paraganglioma.
