Classic biphasic pulmonary blastoma demonstrated by 18F-FDG PET/CT.

A 75-year-old nonsmoker woman was referred for the evaluation of a nonsecretory left adrenal lesion. An abdominal contrast-enhanced CT showed an incidental left lower lobe mass, which was confirmed on a chest contrast-enhanced CT. A 18F-FDG PET/CT showed a hypermetabolic tumor without nodal or distant metastasis. She underwent a lobectomy, and the final pathology reported a classic biphasic pulmonary blastoma, which is an uncommon histological form of malignant lung neoplasm. This case highlighted the glucose avidity of this rare and aggressive cancer.
