Intrarenal varix mimicking a cystic renal tumor

Abstract Background : A case of intrarenal varix in a 60‐year‐old woman is reported. Methods/Results : The preoperative diagnosis was cystic tumor in the central part of the left kidney. Retrospectively, gadolinium‐enhanced magnetic resonance (MR) imaging demonstrated a layered gadolinium sign, indicating the vascular nature of the mass. Conclusions : Our experience shows that urologists should be aware of the possible presence of a renal cystic mass of vascular origin and of the usefulness of gadolinium‐enhanced MR examination for making an identification.
