Simple pulmonary eosinophilia in a 61-year-old man with rectal cancer that mimicked metastasis on both the CT and PET.

A. Transverse CT scan obtained with the lung window setting shows two round nodules in the right lower lobe (arrow) and the left upper lobe (arrowhead).

B. The transverse FDG PET scan shows increased uptake in the nodules with an SUV of 5.3 (arrow) and 3.0 (arrowhead), respectively. The nodules showed complete resolution on the follow-up CT scans performed 2 weeks later (not shown).
