From: Pulmonary artery involvement in Takayasu’s arteritis: diagnosis before pulmonary hypertension
Imaging findings of pulmonary arteritis in patients with Takayasu’s arteritis. a, Axial computed tomography (CT) image shows mosaic perfusion with reduced vessels in the darker lung (right lung), indicating occlusive vascular disease; a thin wall cavity is present in the right upper lung, consistent with pulmonary infarction. b, CT image obtained 2 years later shows a healing residual lesion from the cavity of the right upper lobe; subpleural scarring is also present. c, CT image shows a subpleural wedge-shaped opacity suggestive of pulmonary infarction. d, Contrast-enhanced CT image shows corresponding pulmonary artery occlusion in the right lower lobe. e, CT image shows peripheral scarring from previous infarcts in the right lower lung. f, Coronal reformatted image from CT pulmonary angiography in the same patient as in (e) shows occlusion of the right upper lobe artery and stenosis of the right interlobar artery and lower lobe artery
