Figure 1. Nephrocalcinosis and kidney stones by renal imaging.
Panel A: High attenuation within the kidneys due to nephrocalcinosis is present at the corticomedullary juncture and medulla (arrowhead), while discrete stones are present at the collecting system (arrow). Panels B and C: Nephrocalcinosis by renal ultrasound evidenced by increased pyramidal density (arrowheads) associated with acoustic shadowing. Changes in Panel C are more marked than in Panel B.
