Abstract

The term “milk of calcium” has been borrowed from a somewhat similar condition encountered in the gallbladder. In most cases the condition is asymptomatic and is found only accidentally. In the plain film taken with the patient supine, the appearance suggests an ordinary round or oval solid calculus. However, with the patient upright or sitting, the calcific material gravitates to the bottom of the cyst resulting in the characteristic “half-moon” contour (Figure 1). It was first described by Fresnais1 in 1937. Since then a number of cases (around 30) have been described in the world literature. Most of them showed the milk of calcium either in a calyceal diverticulum or in a pyelogenic cyst2,3, but in several cases it was in hydronephrotic kidneys1,4,5. “Milk of calcium” is made of fine sand-like concretions4,5,6 of calcium carbonate2,3, hydroxyapatite4, calcium oxalate7 or magnesium ammonium phosphate5.
