Fig. 15From: Multimodality imaging of renal lymphoma and its mimicsUrothelial 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 lymphomaBack to article page
