We report a case of renal sinus non-Hodgkin's lymphoma without contiguous adenopathy. Magnetic resonance and computed tomography images of this rare tumor were correlated with a pathologic specimen. On computed tomography the renal sinus lymphoma was evaluated as a well circumscribed, low-density mass owing to the mixture of the lymphomatous cells and fat tissues. Magnetic resonance showed the replacement of the renal sinus fat tissues with a spoke-like solid mass. The renal artery and vein were also evaluated thoroughly and were without tumor thrombosis.
