Case Study

Pyelonephritis in a 12 year old FS Golden Retriever with anorexia and weight loss

A 12-year-old spayed female Golden Retriever dog was presented for anorexia and weight loss. Pyrexia, weak hindquarters, and multiple growths were noted on physical examination. CBC and T4 were within normal limits. Abnormalities on serum biochemistry included azotemia, elevated liver enzymes, and hypercholesterolemia.

Sonographic Differential Diagnosis

Emerging renal failure. Chronic interstitial nephritis with potential concurrent pyelonephritis.

Image Interpretation

The urine presented some mildly echogenic debris consistent with mucous, exfoliated cells from renal or bladder origin, and/or blood clots. This is often related to urinary tract infection (UTI) but may also represent simple evidence of exfoliated debris or sterile inflammation. Cystocentesis, urinalysis, and/or culture would be recommended to rule out and define a UTI. The kidneys presented mildly dilated renal pelvises with moderate chronic degenerative cortical changes. The kidneys were mildly subnormal in size with retraction of the capsular contour. This sonographic presentation is most consistent with chronic interstitial nephritis with potential concurrent pyelonephritis.

DX

Chronic interstitial nephritis with potential concurrent pyelonephritis

Outcome

Three weeks later the patient was not eating the K/D diet and the owner was considering options.

Clinical Differential Diagnosis

Increased liver values – neoplasia, infection (bacterial/viral), toxic, chronic-active hepatitis, abscessation, vacuolar hepatopathy, granulomatous hepatitis. Azotemia – chronic kidney disease, neoplasia, pyelonephritis, renoliths.

Sampling

None.
