A 12-year-old SF Yorkshire terrier was presented for evaluation of hematuria and stranguria. On physical examination weight loss and severe dental disease were present. CBC was within reference range. Azotemia, hyperphosphatemia, and hyperglobulinemia were evident on serum biochemistry. Urinalysis showed hematuria, WBC’s, and SG of 1.020. On radiographs, bronchial pattern, some mineralization in the area of the bladder, lumbosacral spondylosis, and excessive GI gas.
Cystourethral junction urethral mass into iliac lymph nodes and bladder mass all mineralizing strongly suggestive for transitional cell carcinoma.
Urinary bladder presented a polypoid mass occupying the cystourethral junction and trigonal area with focal areas of mineralization which measured approximately 2 x 2.5 cm. The mass enters into the cystourethral junction and expands approximately 1 to 1.5 cm at the proximal urethra. Focal areas of mineralization noted throughout. Concentric infiltrative pattern is noted through the trigone, cystourethral junction and the ventral bladder wall. Approximately 1 cm of the visible urethra was noted and minor thickening was present which could represent seeding. This lesion is non-resectable regardless. Iliac lymph nodes enlarged measuring 1 cm with focal areas of mineralization strongly suggestive for metastatic disease.
