68Ga-DOTATATE PET/CT in Primary Pulmonary Lymphoepithelioma-Like Carcinoma

Primary pulmonary lymphoepithelioma-like carcinomas (LELCs) are extremely rare tumors with better prognosis than other types of lung malignancies. In this case, we present 18F-FDG and 68Ga-DOTATATE PET/CT findings in a 52-year-old woman with pathologically confirmed pulmonary LELC. The pulmonary LELC presented mild 18F-FDG but avid 68Ga-DOTATATE uptake, indicating that the somatostatin receptor 2 may be highly expressed in LELCs. Therefore, 68Ga-DOTATATE PET/CT is a useful tool for tumor detection and initial staging in patients with LELCs.
