Abstract
A 51-year-old woman who had a history of partial nephrectomy underwent an 18F-FDG PET/CT image for a routine health checkup. Focal intense FDG avidity without any anatomical correlation on CT was detected in the lung. On the delayed image after 20 minutes, the focal activity migrated to a more peripheral portion. An iatrogenic microembolus is a rare but crucial false-positive finding that nuclear physicians should be aware of. Our case emphasizes the importance of meticulous FDG injection and cautious interpretation. In addition, delayed PET/CT imaging through wet reading can aid in diagnosing and help prevent unnecessary investigations.
