A first CT scan (Figure 1), performed without contrast, showed a 33-mm spiculated mass of the right lower lobe.
Second post-contrast CT scan, with axial reformations, performed 15 days later showing changes with new central ground glass attenuation (arrow)CT scan examination also showed pulmonary emboli: some clots were central and marginated within the right main pulmonary artery (not shown)

CT scan examination (Figure 2) showed significative changes in the mass, namely the appearance of a central ground glass attenuation.
Third post-contrast CT scan, with axial reformation, performed 3 months later showing total disappearance of the mass (large arrow). There was a complete disappearance of pulmonary emboli (not shown)
