A Rare Case of Primary Pulmonary Epithelioid Angiosarcoma Detected by F-18-FDG PET/CT

We describe a rare case of primary pulmonary epithelioid angiosarcoma detected by F-18-FDG PET/CT. A 54-year-old female patient with history of non-Hodgkin lymphoma underwent F-18-FDG PET/CT for follow-up. PET/CT detected an area of increased F-18-FDG uptake corresponding to a 4-cm mass located in the inferior lobe of the left lung. Based on this PET/CT finding, the patient underwent left inferior pulmonary lobectomy. Histology demonstrated the presence of a pulmonary epithelioid angiosarcoma. Other sites of disease were excluded. In our case, F-18-FDG PET/CT has been useful in detecting and staging this rare primary pulmonary tumor.
