Urothelial carcinoma. Sagittal grayscale ultrasound (a) demonstrates an enlarged right kidney with relative preservation of the reniform shape. Note the diffuse infiltration of the pelvocalyceal system (arrows). Contrast-enhanced axial CT (b) shows the diffuse enlargement of the right kidney with infiltrative tissue centered in the collecting system; subsequent biopsy confirmed urothelial carcinoma, mimicking the diffuse infiltration/nephromegaly pattern of renal lymphoma
