Abstract: To analyze the clinical characteristics,imaging and pathological features of 1 case with partial right lung atelectasis and summarize the relevant domestic reports on the false positive of positron emission tomography-computed tomography (PET-CT) and tumor markers.The patient was diagnosed by PET-CT as partial atelectasis and there were progressive increases of CEA,CA199 and CA242.But site of lesion biopsy showed no malignancy.After treatments of anti-inflammatory and eliminating phlegm,the tumor markers returned to normal and the lesion site had excellent re-expansion.The detection of PET-CT plus tumor markers may have false positive probability.The reason is probably related with inflammation and glandular secretion of lesion site.
