Herein, we present a case of 34-year-old woman who came to our hospital for medical help due to cough and sputum for one month. She underwent a chest computed tomography (CT) scan which revealed a circular soft tissue density shadow in the upper lobe of the left lung. A needle biopsy was subsequently performed which revealed a probable lung carcinoid. To further evaluate the nature of the mass and determine a treatment plan, the patient subsequently underwent dual nuclide tracer including fluorine-18 labeled fluorodeoxyglucose (<jats:sup>18<\/jats:sup>F-FDG) and gallium-68 labeled 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7,10-tetraaceticacid -D-Phel-Tyr3-Thr8-OC (<jats:sup>68<\/jats:sup>Ga-DOTATATE) PET\/CT imaging. The results showed that the lession presented increased both <jats:sup>18<\/jats:sup>F-FDG and <jats:sup>68<\/jats:sup>Ga-DOTATATE uptake, suggesting a neuroendocrine tumor. However, postoperative pathology confirmed that the lesion was PSP. Our case study suggests that PSP may presents varying degrees of increased <jats:sup>18<\/jats:sup>F-FDG and <jats:sup>68<\/jats:sup>Ga-DOTATATE uptake on positron emission tomography (PET)\/CT imaging, which should be considered as one of the differential diagnoses for lung carcinoids.<\/jats:p>","DOI":"10.3389\/fonc.2025.1511595","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T05:23:10Z","timestamp":1740115390000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Case
