Pulmonary haemorrhage associated with idiopathic pulmonary haemosiderosis. a Axial computed tomography (CT) scan at the level of the lower lobes of the thorax (pulmonary window). b Axial CT scan at the level of the upper lobes of the thorax (pulmonary window). The images show diffuse ground-glass opacity associated with fine reticulation, findings characteristic of pulmonary haemorrhage. The predominant findings in the acute phase of idiopathic pulmonary haemosiderosis also include diffuse nodules (black arrows)
