Leptospirosis presenting as diffuse alveolar hemorrhage: case report and literature review.

Abstract

The literature on diffuse alveolar hemorrhage heavily emphasizes the causal role of vasculitides. We present a patient with diffuse alveolar hemorrhage caused by leptospirosis. Although the pathology in leptospirosis occurs secondary to a vasculitic process, this disease is not listed as a cause of diffuse alveolar hemorrhage in the review literature. In the right clinical scenario, the disease should be considered in a patient presenting with diffuse alveolar hemorrhage.
