There is a sizeable heterodense mass lesion at the medial margin of the right lung's lower lobe, extending to the mediastinum and subcarinal area. It involves the bronchovascular bundle of the lower lobe, leading to extensive peripheral atelectasis and collapse and showing intense FDG uptake (SUVmax=18.6).
The mediastinum has an enlarged lymph node with very intense FDG uptake (SUVmax=22.65) in the right upper paratracheal area. Another enlarged lymph node with similar characteristics is noted in the subcarina.
