Hyper/hypoechoic striations in renal cortex

  • 7 year old MN mixed breed dog with a hx of mild elevated liver values, owner wishing to be proactive with u/s. Labwork otherwise normal. 
  • No clinical signs. Labwork was run to prepare for dental COHAT.
  • U/s was basically NSF. 
  • In both kidneys, there were subtle peripheral cortical striations which were both hyper and hypoechoic (running parallel to each other).
  • Bladder was normal.
  • I’m not sure whether to interpret as anything in lieu of clinical signs and biochem abnormalities. Any thoughts?

  1. Interesting striations Liz,

    Interesting striations Liz, I’ll ping a SP guru for some insight for you!  Question, how was the blood flow in this kidney? particularly in those regions? 

  2. In older resolution we didnt

    In older resolution we didnt this well but with newer machines we are. Microinfarcts/scarring or early mineralization and if in spleen too often cushings will start like this.. its the sonographers calcinosis cutis just in the renal cortex and spleen.

    • Hi Amanda, Blood flow was

      Hi Amanda, Blood flow was normal. 

      Eric, Interesting. I’ll have to go back and look at the case and see if HAC was on the ddx list. I have definitely seen the mineralization with HAC in spleen but I haven’t seen it present this way.

      Thanks for taking a look.
