Case Study

09-00092 Misha M Prostatic TCC——–NEED CDX———-

The patient is a canine Bernese Mountain Dog, intact male, 10 years-old. There is concern for TCC vs prostatic disease, mild transitional cell atypia. Urine specific gravity 1.046, 4+ blood.

DX

Prostatic TCC

Sonographic Differential Diagnosis

Enlarged mineralized prostate. Suspicious for prostatic carcinoma. FNAs were performed without complication. If prostatic carcinoma is confirmed, the following information may prove fruitful. Ultrasound-guided drainage of the cystic portion of the prostate may allow for minor palliative reprieve. If by chance the aspirates are non neoplastic then neutering is recommended as well as prostatic drainage.

Image Interpretation

The urinary bladder itself appeared unremarkable. However, the prostatic urethra was completely obliterated.
The testicles in this patient presented a minor hypoechoic nodule in the middle of the left testicle and measured 0.8 cm. The prostate in this patient presented a 4.9 x 2 cm anechoic cyst at the cranial aspect of the prostate. However, much of the prostate was significantly mineralized. This is consistent with dystrophic mineralization bringing the possibility of transitional cell carcinoma or prostatic carcinoma high on the list as a possibility. Capsular expansion was noted with minor, regional inflammatory pattern. The prostate itself measured 6-8 cm in length.
