The creatinine was 1.46 mg/dL (Figure 1), calcium 13 mg/dL, ionized calcium 7.1 mg/dL (normal 4.6 to 5.3 mg/dL), phosphorus 3.3 mg/dL, PTH 3 pg/mL (normal 9-52 pg/mL), 25 hydroxy vitamin D 18 ng/mL (normal 30-100 ng/mL), alkaline phosphatase 110 IU/L, sodium 135 meq/L, potassium 4.8 meq/L, chloride 103 meq/L, bicarbonate 24 meq/L, BUN 20 mg/dL, albumin 4.5 g/dL, and TSH 0.42 uIU/mL.
Renal ultrasound. (a) Sagittal left kidney: echogenic pyramids, punctuate hyperechoic foci in cortex, comet tail artifact (black arrow outlined in white), and small cyst with through transmission (white arrow with black outline). (b) Sagittal left kidney: echogenic pyramids with many punctuate hyperechogenicities. Two tiny sonolucent cysts with through transmission (black arrows with white outlines). (c) Sagittal right kidney: many punctuate cortical hyperechogenicities. (d) Transverse right kidney: generally increased cortical echogenicity (star) relative to adjacent liver (triangle).

A renal ultrasound (Figure 2) showed bilateral punctate hyperechogenic foci, small cysts, and extensive hyperechogenicities in both cortex and medulla.
