Extra- adrenal retroperitoneal @entity1823 are @entity395 with an incidence of 2-8 per million. They arise from embryonic neural crest cells and are composed mainly of chromaffin cells located in the para- aortic sympathetic chain. They synthesize, store and secrete catecholamines because of which they may present with @entity10 , sweating, palpitation and symptoms of @entity101 . On the other hand, they may remain silent and non- functional and present with vague symptoms like @entity158 abdomen due to episodic release of catecholamines. Histologically and immunohistochemically, non- functional and the functional @entity5 are no different from each other. Primary methods of pre-operative diagnosis include imaging techniques which also help in surgical planning and pre-operative preparation. @entity5 of ten escape pre-operative detection and create per- operative complications. We present a case of non- functional @entity3506 occurring in a 66-year-old female @entity1 presenting with @entity158 and mass per abdomen. On ultrasonongraphy, a retroperitoneal mass of probable mesenchymal origin was suspected. The @entity1 was posted for surgical resection of the mass. Per-operatively, the @entity1 developed @entity101 crisis and @entity548 . Post-operatively she developed @entity177 and succumbed to it after three days. This report highlights the importance of pre- operative diagnosis which is vital in the management of @entity3506 .
