Figure 1.
Axial CT images on soft-tissue and lung window settings on post-contrast CT (A) and the CT component of a non-contrast PET-CT (B) performed 6 weeks later, which show an enlarging low-density pulmonary nodule within the lower lobe of the right lung. Note that image A suggests the presence of macroscopic fat anteriorly within the lesion. PET, positron emission tomography.
