Diffuse Alveolar Hemorrhage Due to Warfarin Overdose

Abstract

Warfarin is one of the most common oral anticoagulant used today. Although bleeding is the primary adverse effect of warfarin, diffuse alveolar hemorrhage is a rare condition. Here we report the clinical and imaging findings of a 53 year-old male patient who rapidly developed diffuse alveolar hemorrhage after an overdose of warfarin for mitral stenosis and atrial fibrillation.
