A 64-year-old man was referred to our center for metabolic characterization of 2 bilateral pulmonary lesions, incidentally detected at computed tomography (CT). 18F-FDG PET/CT scan showed a weak radiopharmaceutical uptake in both pulmonary lesions. A subsequent 68Ga-DOTANOC PET/CT showed intense radiopharmaceutical uptake in both pulmonary lesions. Subsequently, the patient underwent histopathological examinations of both lesions, which showed a synchronous well-differentiated pulmonary neuroendocrine carcinoma (typical carcinoid tumor). This case reports a rare occurrence of synchronous pulmonary carcinoid, highlighting the role of different PET tracers for metabolic characterization of pulmonary nodules.
