Case Study

Prostatic carcinoma diagnosed by FNA in a 15 year old MN West Highland White Terrier dog

A 15-year-old NM West Highland White terrier dog was presented for evaluation of polydipsia, polyuria and possible bladder stones noted on radiographs. Abnormalities on CBC and serum biochemistry were thrombocytosis, neutrophilia, and hyperalbuminemia. Urinalysis was not performed owing to financial constraints however an abdominal ultrasound prescription was approved.

Sonographic Differential Diagnosis

These images are suggestive of a mineralizing prostatic mass as opposed to luminal urethal calculi. Specifically carcinoma is suspected.

Image Interpretation

The prostate revealed a large mineralizing mass that measured 4.4 x 2.7 cm with extrusion of the mass into the pre-prostatic urethra. Prostatic capsular expansion and distortion is noted

DX

Prostatic carcinoma

Outcome

Client is considering euthanasia as the patient has not been doing well. No further outcome.

Comments

Empirical therapy with Deramaxx and enrofloxacin would be recommended until an oncology consultation can be considered.

Clinical Differential Diagnosis

Polydypsia – bladder pathology (uroliths, neoplasia, chronic cystitis, bacterial cystitis), prostatic neoplasia, renal pathology (early chronic kidney disease, neoplasia, pyelonephritis).
