Abstract: | Primary pulmonary lymphoepithelioma-like carcinoma is a very rare subtype of lung cancer. This report documents the CT features of 16 Chinese patients diagnosed with primary pulmonary lymphoepithelioma-like carcinoma from January 1999 to December 2005. A pre-treatment CT was used to assess the tumour site, size, borders, pleural and vascular involvement, and the presence of lymph node involvement. The majority of the patients were female non-smokers with centrally located tumours. Lymph node involvement and bronchial and vascular encasement were frequent. In an Epstein-Barr virus endemic area, primary pulmonary lymphoepithelioma-like carcinoma is an important differential diagnosis to consider. |
