2. Figure 40A and B What do you see in her kidneys?
The CT scan showed bilateral hyperdense material in calyces and renal pelvis with fluid-to-fluid levels, but no stones.
The patient’s serum calcium level was 9.0 mg/dL (2.25 mmol/L), urine calcium level was 8.3 mEq/24 h, and urine pH was 6. The patient was treated with ciprofloxacin (1 g/d) and saline hydration. The CT scan was repeated after 7 days, and the hyperdense material and fluid-to-fluid levels had resolved. Findings of metabolic evaluation for causes of nephrolithiasis were normal. The CT changes initially observed were attributed to transient saturation of calcium salts caused by dehydration in the course of fever, possibly facilitated by the urinary infection. This is referred to as “milk of calcium,” represented by colloidal suspension of calcium crystals.
