18F-FDG PET/CT Revealed of Rare Primary Lyphoepithelionma-Like Carcinoma of the Lung: A Case Report and Literature Review


We present a case of a 44-year-old woman was hospitalized for one year with intermittent coughing and expectoration. She has no history of smoking or previous medical conditions. DNA test positive for Epstein-Barr virus. Chest computed tomography (CT) showed a soft tissue mass in the left lower lobe of the lung and non-uniformity of image density. Part of the bronchus in the lower lobe of the left lung was compressed and occluded. On contrast-enhanced CT, the mass was inhomogeneously enhanced. Fluorine-18-fluorodeoxyglucose positron emission tomography/ CT (18F-FDG PET/CT) revealed the mass had significant uptake of FDG and maximum standard uptake value (SUVmax) was 10.7. The subsequent histopathologic examination confirmed the diagnosis of a primary lung lyphoepithelionma-like carcinoma (LELC). The patient was treated with chemotherapy.
