Imaging Characteristics and Prognostic Value of Isolated Pulmonary Metastasis from Colorectal Cancer Demonstrated with18F-FDG PET/CT
Figure 2
18F-FDG PET/CT findings of pulmonary lesions of PLC (a), atypical pulmonary metastasis of CRC (b), and atypical benign nodule (c). (a) A 68-year-old man with a history of rectal carcinoma. 18F-FDG PET/CT revealed a pulmonary lesion with air bronchogram (SUVmax, 8.4; Dmax, 24 mm). The patient underwent pulmonary surgery. Pathological examination confirmed PLC. (b) A 64-year-old man with a history of rectal carcinoma. 18F-FDG PET/CT revealed a pulmonary lesion that was suspected to be malignant (SUVmax, 9.93; Dmax, 32 mm). Pulmonary surgery confirmed pulmonary metastasis. (c) A 62-year-old man with a history of rectal carcinoma.18F-FDG PET/CT revealed a pulmonary lesion that was suspected to be malignant (SUVmax, 3.84; Dmax, 14 mm), pleural indentation, and spiculation. Pulmonary surgery confirmed inflammatory disease.
