Transitional Cell Carcinoma (TCC) in a 12 year old FS Chow dog

Case Study

Transitional Cell Carcinoma (TCC) in a 12 year old FS Chow dog

A 12-year-old FS Chow was presented for evaluation of persistent hematuria and stranguria. Urinalysis showed low-normal SG (1.020), hematuria, and leucosuria. Mildly elevated ALP activity was present on blood work.

Sonographic Differential Diagnosis

Bladder mass.
Concurrent small bladder calculi.
Left lateral liver nodule.

Image Interpretation

The cystourethral junction and trigone in this patient revealed a 3 x 1.69 cm mineralizing mass obstructing the left ureter; it entered into the cystourethral junction. It is not resectable at this time; however would be amenable to ultrasound guided laser ablation at Ridgewood Veterinary Hospital, Ridgewood, NJ. Decompression of the ureter could be performed by laser ablation plus or minus ureteral stent placement.
Left liver presented a 1.35 cm mixed hyperechoic nodule that appears to be isolated. The remainder of the liver appeared unremarkable.

DX

TCC

Outcome

None

Comments

Fine needle aspirates recommended of the general liver as well as the liver nodule itself. No overt evidence of metastatic disease noted unless the left liver nodule represents a metastatic lesion; however this would be an odd pattern for transitional cell carcinoma for metastasis in my opinion.  

Clinical Differential Diagnosis

Bladder pathology– urolith, neoplasia, bacterial cystitis, polyploid cystitis;
Urethral pathology– lith, neoplasia, granulomatous urethritis
