case_images: The resection margin was free from carcinoma, although there was metastatic carcinoma in one out of two lymph nodes (pT3N3 M0) (Figure 1A). A lung metastasis was confirmed to be urothelial cancer after a percutaneous transthoracic needle biopsy (Figure 1B) performed on a left lower lobe posterior segment metastatic lesion.
case_images: A, B: Chest CT demonstrating hematogenous metastastatic nodule in RML (arrow, A) disappeared after 4th FOLFOX4 cycles (B). C, D: Chest CT demonstrating hematogenous metastastatic nodule in LLL (arrow, C) that formed fibrotic cavity after 4th FOLFOX4 cycles (D).

case_images: Moreover, multiple lung metastases were seen on chest CT (Figure 2A, 2C). After four rounds of chemotherapy, the lung metastases all disappeared, except one fibrotic cavitary lung lesion (Figure 2B, 2D).
case_images: A: PET CT demonstrating no metastatic lesion after 8th FOLFOX4 cycles. B: PET CT demonstrating no FDG upake in the lung include left lower lobe.

case_images: Abdominal and chest CT performed after eight rounds of chemotherapy still showed no metastatic lesions, and positron emission tomography-computed tomography (PET-CT) showed no metastatic lesion (Figure 3A), with no 18F- fluoro-2-deoxyglucose (FDG) uptake in the fibrotic cavitary lesion in the lung (Figure 3B).
