Renal medullary striations in a cat

  • 8 year old mn Siamese presented to primary vet for chronic vomiting (3 weeks)
  • Bloodwork performed 3-26-20 showed WBC=29.4 K/mcl, PMN=24.7 K/mcl, Mono=0.588K/mcl
  • Chem prof is wnl including the SDMA, T4=1.1mcg/dL, U/A not performed

    • Abdominal US shows bilateral renal medullary echogenic linear striations,  slightly decreased left pancreatic echogencitity but normal shape, size, and no peripancreatic inflammation, echogenic GB wall with normal thickness, small size and normal content, and mildly fluid distended intestines (no obstructions, normal wall layering, normal wall thickness).
    • What are your differential diagnoses for the medullary striations?  calcification?  infection?  neoplasia?

We just call them vertical

We just call them vertical corticomedullary striations… idiopathic. I checked with Nele ( https://sonopath.com/about/specialists/nele-ondreka-dvm-dr-med-vet-dipecvdi) as well and this is what she calls them too. I think I would emphasize them more if inflammatory sediment is in the urine but I’ve seen them in nsf cats as well. Curvilinear patterns are conserved elsewhere in the kidneys so I doubt neoplasia.

Not sure if similar but

Not sure if similar but striations are descibed in humans with excretory urography and are associated with either a previous obstructive episode or chronic obstruction. In an experimental  dog model of ureteric obstruction dense striations have been reported. Reported etiology is that the striations represent shadows produced by hyperconcentrated contrast material that has accumulated in the dilated collecting ducts or groups of ducts within the medullary rays. Maybe what we see on US is cellular urine within the ducts giving a similar picture as on contrast.
