Benign infectious or inflammatory processes can cause false-positive results in oncological PET-CT imaging, through the 18F-FDG metabolic activity they exhibit. The sequential PET/CT evaluation of post-infection COVID-19 in a patient with a pathological history of breast neoplasm has questioned the importance of PET/CT in tracking cancer versus scarring processes in COVID-19. It is not usual in medical practice to follow up a case with COVID-19 post-infection status by PET/CT examination, even less so by two PET/CT examinations performed at two months and three months post-infectious episode respectively, which is why the importance of publishing this article was decided.
