Découverte fortuite d’un phéochromocytome en peropératoire

We here report an unusual case of ectopic pheochromocytoma without the presence of any clinical symptoms. Radiological examinations showed tumor in contact with the pancreas. Intraoperatively, after surgical manipulation of the tumor, the patient had tachycardia, hypertensive peaks and severe ventricular rhythm disorders followed by hypotension after tumor resection and shock. The management of severe intraoperative adverse events revealing pheochromocytoma is discussed in this case study.
