Medullary Nephrocalcinosis

General Considerations

  • Increased calcium content of kidneys
    • Usually applies to a generalized, rather than localized, increase in renal calcium content
  • Macroscopic nephrocalcinosis is nephrocalcinosis visible without magnification discovered by radiography, ultrasonography, or at autopsy
  • Macroscopic nephrocalcinosis can affect either cortex or medulla
    • Medulla more common
    • Diffuse calcification rarely observed in chronic glomerulonephritis or long-standing chronic renal disease
