Moderately differentiated adenocarcinoma (SUVmax 6.9) of the upper lobe of the left lung with benign bilateral mediastinal nodes: SUVmax 4.5 (SUVmax liver 3) and pleural effusion; even if the SUV value of nodes is higher than the liver uptake, the pattern of symmetric FDG uptake helps to suspect inflammatory condition. In patients with an imaging finding suggestive of metastasis, further evaluation of the abnormality with tissue sampling to pathologically confirm the clinical stage is recommended prior to choosing treatment.
