Nephromegaly of renal lymphoma. Coronal noncontrast CT (a) demonstrates symmetric marked enlargement of the bilateral kidneys from lymphomatous infiltration in this patient with mantle cell lymphoma. Concurrent PET/CT in 9/2020 (b) demonstrates marked F18-FDG avid bilaterally enlarged kidneys as well as extensive supradiaphragmatic and infradiaphragmatic lymphadenopathy. Follow-up F18-FDG PET/CT in 11/2020 (c) following chemotherapy shows complete metabolic and radiologic response with normalized renal size and activity
