[A case of negative pressure pulmonary hemorrhage associated with upper-airway obstruction due to a giant vocal cord nodule].

Abstract

A 68-year-old woman was brought by ambulance because of sudden choking sensation and dyspnea after coughing. A physical examination showed hoarseness and blood-stained sputum. A chest computed tomography (CT) showed bilateral diffusely-distributed ground-glass opacity. A bronchoscopy examination revealed a large nodule on the left larynx and bloody bronchoalveolar lavage fluid. We diagnosed negative pressure pulmonary hemorrhage (NPPH) based on suspected upper-airway obstruction, but it resolved without further treatment. We found no other causes. We report a rare case of NPPH due to a giant vocal cord nodule.
