Renal urolithiasis vs. dystrophic mineralization


  • 11 year old FS DSH with history of weight loss, chronic intermittent vomiting, and renal disease.  Recent episode of UTI being treated with Convenia.  
  • Abdominal US showed a slightly increased small intestinal muscularis to mucosal ratio and mildly reactive colic lymph nodes consistent with IBD or early LSA.  The caudal half of the left kidney shows a hyperechoic medullary band. Color flow Doppler was negative for blood flow over the lesion.

    • Just wondering how to describe this change in the kidney.  Would you call this a stone or dystrophic mineralization?

    Good question! For that one I would say calculus in renal calix, meaning high up in the “fingers” that drain in pelvis.
    But I might be using the wrong term ( when I say calix). I look Forward to hear what others say.
    I find dystrophic mineralization tends to be less discrete. More like specks without that much distal shadowing. Again, I might be wrong…let’s see what the experts say.
