Milk of calcium of the kidneys and nephrolithiasis are two different entities. Milk of calcium in the pelvicalyceal system can mimic calculus and contrast in the pelvicalyceal system if bilateral. Their differentiation is important as their management differs. It can be seen in the urinary tract, in the GIT, bronchogenic cyst and adrenal cyst. The usual feature of milk of calcium is low calcium density in relation to apparent size, fuzzy, indistinct margins of calcifications, unusually large size of calcification, nearly circular shape of calcification and movement with gravity, atypical location of calcium density in relation to kidney. Milk of calcium primarily consists of small crystals of calcium carbonate. However, calcium oxalate, calcium phosphate, calcium hydroxyapatite and ammonium phosphate can also contribute to milk of calcium. We report a case of 25-year-old male patient whose computed tomography (CT) of abdomen showed hyperdensities within calyces of both kidneys extending into bilateral renal pelvis and left upper ureter mimicking contrast in pelvicalyceal system.
