CT Contrast IMPRESSION: Multiple well marginated soft tissue nodules and masses of variable sizes in bilateral lung parenchyma, with a dominant nodule in right lower lobe - pulmonary metastases may be considered Mild centriacinar emphysematous changes in bilateral lung parenchyma. Few prominent / mildly enlarged bilateral hilar nodes. > Minimal pericardial effusion. > Small hiatus hernia. PET CT IMPRESSION: FDG avid poorly marginated mass in medial basal segment of right lower lobe infiltrating oblique fissure with minimal extension into right middle lobe- likely lung carcinoma/ metastasis FDG avid bilateral pulmonary nodules - likely metastases FDG avid mediastinal lymph nodes - suspicious for metastases FDG avid nodules in bilateral adrenal glands - likely metastases Non FDG avid ill-marginated enhancing lesion in left parietal lobe - metastasis (adv: MRI correlation) Biopsy says Pulmonary Adenocarcinoma. Please help me knowing the stage and severity.
