Renal involvement in lymphoma: prevalence and various patterns of involvement on abdominal CT

Abstract

Five distinct patterns of renal involvement with lymphoma were detected with helical CT. The most common appearance was enlarged lobular kidneys. CT with intravenous contrast enhancement is currently the approach of choice for both the evaluation of renal involvement as well as for accurate staging of lymphoma. Awareness of different patterns of renal involvement in lymphoma allows proper differentiation from other similar diseases.

“…Other US features are absence of a mass effect on renal vessels and pelvicalyceal system and absence of calcification [32,33]. Renal metastases may present as solitary, multiple, or infiltrative masses.…”

Renal Mass Biopsy

“…However, renal lymphoma is detected on routine abdominal imaging in only 2.7-15 % of patients who undergo computed tomography (CT) scans during lymphoma staging investigation [ 16 , 17 ]. The discrepancy between actual cases and imaging-detected cases of renal lymphoma during staging may be due to variations in the radiological appearance of renal lymphoma; on imaging, the appearance of renal lymphoma can vary from a well-defi ned mass resembling primary renal tumors to diffuse involvement and enlargement of the kidney [ 18 ]. Image-guided biopsy can help differentiate renal lymphoma from epithelial tumors of the kidney (Fig.…”
