Cancer

Large Renal Cell Carcinoma Extending beyond the Renal Capsule
On CT there is dystrophic calcification. On angiography there is hypervascularity, neovascularity, AV shunting. Excretory phase after angiography shows distorted calyces

CT with Contrast? Polycystic Kidney Disease PCKD
56-year-old male in chronic renal failure presents with flank pain. CT with contrast shows diffuse cystic changes of near normal sized kidneys with total replacement of the renal parenchyma by small uniformly sized cysts. Multiple calcifications are scattered throughout the parenchyma.

Metabolic Causes

Lithium

51 year old female with bipolar disorder on Lithium
CT shows numerous punctate calcifications in the cortex
and medulla bilaterally. Given history of lithium usage, CT appearance can be
seen with lithium-induced renal disease.
