Milk of calcium cysts of the kidneys

Milk of calcium cysts must be differentiated from more ominous conditions like kidney stones and angiomyolipoma (a relatively common kidney tumor). These ultrasound videos show the typical feature of milk of calcium cysts- their tendency to gravitate to the dependent part of the cyst on postural change.

The video clip above shows the calcium salts in the right of the cyst (viewer's right), in the sitting posture.

Now observe the 2nd sonographic video clip above: the milk of calcium has shifted in position with change of the patient's position to the right lateral decubitus position.
