[Intermittent chronic occlusion of the duodenum caused by pheochromocytoma].

A case (63 y. old male) of intermittent duodenal obstruction is presented. Aortographic investigation showed a neoplastic mass in the right adrenal gland. At laparotomy the mass, histologically diagnosed as a pheochromocytoma, appeared to infiltrate the duodenal wall, displacing it upward. Though gastrointestinal disturbances have been frequently recorded in pheochromocytoma, as far as we know this is the first description of intermittent duodenal obstruction in this disease.
