Increased Neutrophils in Bronchoalveolar Lavage Fluids from a Patient with Pulmonary Edema Associated with Pheochromocytoma

Abstract

Pulmonary edema, both cardiogenic and noncardiogenic, has been reported as a manifestation of pheochromocytoma. We report a patient with pheochromocytoma complicated by acute pulmonary edema that appeared clinically noncardiogenic. The patient had an uncomplicated course and rapid resolution of pulmonary edema. Bronchoalveolar lavage fluids (BALF) showed a marked accumulation of neutrophils, suggesting involvement of neutrophil-mediated lung injury in noncardiogenic pulmonary edema associated with a pheochromocytoma.
