Pheochromocytoma presented as intestinal pseudo-obstruction and hyperamylasemia.

Abstract

Pheochromocytoma has wide variations in alimentary presentations and complications. Here, we report a patient with pheochromocytoma who developed intestinal pseudo-obstruction and hyperamylasemia. The intestinal pseudo-obstruction responded promptly to intravenous infusions of phentolamine, an alpha-adrenergic blocker managed to control hypertensive crisis. The hyperamylasemia regressed gradually after resection of the tumor. The role of catecholamines liberated from the tumor is discussed in the associated pathogenesis. Early recognition of pheochromocytoma with gastrointestinal manifestations will facilitate proper management and prevent possible lethal outcome.
