The contrast-enhanced CT showed right upper pulmonary arterial stenosis and main pulmonary artery dilation (Fig. 2).
(A) Lung ventilation scintigram showing no abnormality. (B) Lung perfusion scintigram showing a perfusion defect in the right upper lobe. (C) Pulmonary angiogram revealing right upper pulmonary artery occlusion. (D) Coronal slice image of the chest CT. The right upper pulmonary artery was compressed extrinsically without thrombi.

A lung ventilation scintigram showed no abnormality (Fig. 3A). However, a lung perfusion scintigram showed a perfusion defect in the right upper lobe (Fig. 3B). A pulmonary angiogram revealed right upper pulmonary artery occlusion without thrombi (Fig. 3C). In a coronal slice image of the chest CT, the right upper pulmonary artery was compressed extrinsically (Fig. 3D).
Bronchoscopic images demonstrating bronchial stenosis with carbon powder deposits (anthracofibrosis), mainly in the right upper lobe. (A) Right main bronchus. (B) Right second carina.
