Computed tomographic images obtained at diagnosis (a-c) and after 4 months (d-f). a and b The first computed tomograms of the chest show a ground-glass aspect that is most pronounced in the apical areas with a diffuse reticular aspect and widening of interlobular septa. At this time, the groundglass was mainly localized around bronchovascular bundles. c and f The skeleton shows multiple focal sclerotic lesions. d and e Computed tomographic scans obtained 4 months after the first ones show progressive and diffuse reticular ground-glass lesions
