Usefulness of staging chest-CT in patients with operable breast cancer
Fig 5
CT and fluorine 18 fluorodeoxygluocose (FDG) positron emission tomography (PET)/CT images of a true lung metastasis of a 71-year-old female with pathologic stage III breast cancer.
(a) Staging chest-CT image shows an enhancing indeterminate nodule (arrow) in left upper lobe lingular segment. In addition, descending thoracic aortic aneurysm was incidentally detected. (b) A follow-up chest-CT image shows an interval growth of nodule (arrow). (c and d) Axial and coronal FDG PET/CT scans show FDG uptake in a growing nodule in the left upper lobe lingular segment (SUVmax, 7.7) and multiple axial bony thorax (SUVmax, 12.1). The bony lesion of the left ilium (not shown) was pathologically confirmed as metastasis after CT-guided biopsy. The nodule in the left upper lobe lingular segment was subsequently regarded as pulmonary metastasis.
