Template:CT of peripelvic cysts - description

A case of a 71 year old man with slightly elevated creatinine. A non-contrast CT scan shows fluid-attenuating volumes by the renal pelvices, which could be hydronephrosis. However, CT urography shows normal size of renal calyces and penvices, and the volumes are thus parapelvic renal cysts. Coronal planes:

• 
  Non-contrast CT
• 
  CT urography
• 
  Combined
