CT scan of the chest showed diffuse ground glass opacities and bilateral patchy consolidation (Figure 1(a)). His symptoms improved with complete resolution of alveolar hemorrhage on chest CT scan after 2 weeks (Figure 1(b)).
Bronchoalveolar lavage (BAL) revealed increasing blood in four sequential aliquots confirming diagnosis of diffuse alveolar hemorrhage (DAH).

He underwent right wedge resection lung biopsy which revealed evidence of bland pulmonary hemorrhage (Figure 3(a)) with no evidence of capillaritis or diffuse alveolar damage (DAD). Prussian blue iron staining was also noted which reflects old hemorrhage (Figure 3(b)).
