  • Figure 1
    Initial Chest X-Ray

    Chest X-Ray showing two nodular opacities in the left lower zone (red arrows). Ill-defined pleural thickening is also demonstrated. Angular blunting of the left costophrenic angle may suggest pleural thickening over...

     
    Area of Interest: Education; Imaging Technique: CT; Procedure: Education; Special Focus: Inflammation;
     
     
  • Figure 2
    CT Diffuse pleural thickening

    Axial CT showing smooth pleural thickening >3mm extending >5cm laterally. Retropleural fat is seen (white ovals), likely due to pleural retraction. Parenchymal bands (red ovals) and foci of folded lung (red square)...

  • Figure 3
    Diffuse pleural thickening

    Coronal (left image) and sagittal (right image) CT reconstructions demonstrating diffuse pleural thickening extending >8cm craniocaudally (red oval). Costophrenic angle blunting is shown (red square). No mediastinal...

  • Figure 4
    Round atelectasis

    Axial CT reconstruction showing foci of round atelectasis (red arrows), accounting for the nodular opacities visible on figure 1. Note the subtle converging/bending of bronchovascular structures towards the areas of...

Chest X-Ray showing two nodular opacities in the left lower zone (red arrows). Ill-defined pleural thickening is also demonstrated. Angular blunting of the left costophrenic angle may suggest pleural thickening over pleural fluid (red square).
