FIGURE 2.
Eighty-two-year-old female with growing right lung nodule. Prior lung CT scans over a 1-year period had demonstrated increasing size of a spiculated-appearing right lung nodule (white arrow). FDG-PET/CT was performed for nodule characterization. Images show corresponding transaxial planes through the chest from the CT and FDG PET (upper right); and a 3D maximum intensity projection imaged centered on the chest region (center image). PET showed detectable, albeit minimal, activity in the right lung nodule (black arrows; SUVmax 2.1) and focal activity in the right pulmonary hilum (arrowhead) thought to represent lymph node FDG uptake. Wedge resection was performed; pathology found focal bronchopneumonia/granuloma.
