title: Primary Pulmonary Low-Grade Angiosarcoma Characterized by Mismatch between ¹⁸F-FDG PET and Dynamic Contrast-Enhanced CT.
abstract: We report a rare case of primary pulmonary low-grade angiosarcoma on dynamic contrast-enhanced CT and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT imaging. A 38-year-old, asymptomatic woman was hospitalized because of an abnormality on chest radiography. A dynamic contrast-enhanced chest CT showed a 1.2 cm-sized irregular-margined nodule with strong and persistent enhancement in the right lower lobe. The lesion had low metabolic activity on an (18)F-FDG PET/CT scan. The patient underwent a wedge resection for the lesion, and pathology revealed a primary pulmonary low-grade angiosarcoma.
