Intrarenal varix mimicking a cystic renal tumor.
BACKGROUND
A case of intrarenal varix in a 60-year-old woman is reported.


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.
