Noradrenergic Pheochromocytoma: A Case Report.

Pheochromocytomas and paragangliomas are rare neuroendocrine tumors developed from chromaffin cells. They are exceptional in children with an atypical symptomatology. We report here a case of a 17-year-old boy who presented with a left retroperitoneal mass discovered on thoracic-abdominal-pelvic computed tomography (CT) scan in the presence of diffuse abdominal pain, more pronounced in the left hypochondrium.
