Figure 5: Chest X-ray and tomography: chest X-ray revealed ill-defined opacities in both lungs, especially in the middle and inferior field of the right lung (a). There was no mediastinal enlargement, a remarkable sarcoidosis radiographic sign. Axial high-resolution computer tomography (HRCT) scan revealed multiple ground-grass opacities in bilateral subpleural areas, associated with interlobular septal thickening (b).
