ABSTRACT
Extra adrenal pheochromocytomas (EAPs) commonly arise in the organ of Zuckerkandl. There presentation symptoms are similar to pheochromocytomas. Biochemical investigation demonstrating elevated blood and urine catecholamines and there metabolites along with imaging studies such as ultrasonography (USG) ,CT, MRI and 131I labeled MIBG (meta-iodobenzylguanidine) scan help in achieving the diagnosis.We present a 35 yr old adult female, who presented with severe headache, abdominal pain and episodes of vomiting , examination revealed a firm to hard retroperitoneal mass right to umbilicus, she was hypertensive and had raised urinary VMA. Clinically an extra adrenal paraganglinoma was suspected . USG abdomen and CT guided FNAC confirmed the diagnosis.Tumor was removed with right mid laparotomy leading to cure of disease.
