Discussion (Related Text)

Diffuse pulmonary hemorrhage (DPH) is a sub type of pulmonary hemorrhage,where bleeding into the lung is diffuse. If the bleeding is into the alveolar spaces this can be further sub classified as diffuse alveolar hemorrhage. While the exact presentation can vary is has been classically associated with dyspnea in the setting of hemoptysis. It can occur with a number of causes which include vasculititis (Wegeners granulomatosis, Goodpasture syndrome), connective tissue disorders (systemic lupus erythematosus ), coagulative disorders, medications, inhaled toxins. Plain film demonstrates bilateral air-space consolidation with relative apical sparing. Chest ct may show areas of widespread ground glass opacity, crazy paving pattern , consolidation. In the sub acute phase HRCT may show fine diffuse nodular densities. In later stage there may also be evidence of interlobular septal thickening due to intralymphatic accumulation of haemosiderin.
