The tumour was extending through the dilated ureter up to the left vesicoureteric junction with a focal intraluminal projection into the bladder (Figures 1-4).

(A) Coronal MPR image showing the tumour replacing the entire left kidney (arrows) along with a dilated ureter filled with multiple nodular deposits (arrowheads). Enlarged hilar nodes are also visualized (curved arrow). (B) Sagittal MPR image showing ureteric and renal pelvis dilatation with multiple tumour deposits (arrowheads).

The tumour was extending through the dilated ureter up to the left vesicoureteric junction with a focal intraluminal projection into the bladder (Figures 1-4). Additionally, there were multiple enlarged lymph nodes in the retroperitoneal and renal hilar locations with the largest node measuring 1.7 cm (Figure 3).

Haematoxylin and Eosin stain (10x) shows tumour composed of cells with abundant clear cytoplasm and nuclei with moderate pleomorphism. Neutrophils are seen between the tumour cell lobules.

Sections examined from hilar vessels were free from tumour (Figures 5, 6).
Haematoxylin and Eosin stain (10x) of a section from the resected margin of the ureter shows luminal dilatation, attenuated transitional cell lining epithelium and presence of tumour in the lumen.
