A 6-year-old intact male Doberman pinscher presented with a thin soft stool and urinary signs. On radiography, three masses were observed in the caudal abdomen. One mass was described as a large, round, mineralized mass, with an "eggshell" appearance. The second mass was located caudal to the mineralized mass, and the third mass was located between the two masses. The second and the third masses had a soft tissue density. Ultrasonography was performed to identify the features and the origins of the masses. The first mass contained a large amount of anechoic fluid and had a thin wall; it was determined to be a cyst. Strong acoustic shadowing artifact was created by the mineralized cystic wall. Caudal to the cyst, the second mass was shown to be the prostate. A hypoechoic stalk connected the prostate and the cyst, which represented the cyst as a paraprostatic cyst with mineralization. The third mass was the normal urinary bladder. The cyst was removed surgically and confirmed by histopathologic examination. This report described typical clinical findings, diagnostic imaging, and treatment of a paraprostatic cyst.

A 6-year-old intact male Cane Corso dog weighing 40 kg with a 2-month history of dysuria, dyschezia, anorexia, intermittent panting, and penile discharge presented to the Veterinary Medical Teaching Hospital of Jeju National University. Examination revealed a giant paraprostatic cyst (PPC) that occupied a large part of the abdomen and caused displacement of organs. Radiography, ultrasound, and computed tomography (CT) scans confirmed that the PPC had spread to the pelvic regions. Subtotal resection was performed, leaving two sites with PPC remnants. One site was the prostate gland, which communicated with, and adhered to, the PPC; the other site was the pelvic region, where the PPC had spread. The reason for leaving two remnants was that an anatomical approach for complete resection was difficult, and to avoid complications associated with prostatic urethra damage. Routine omentalization and castration were performed. Partial cystectomy was performed because of the presence of a diverticulum-like lesion in the ventral part of the urinary bladder. The patient's clinical symptoms, including dysuria, completely resolved, and voluntary urination was possible 1 day post-operatively. Histopathological examination revealed osseous metaplasia of the PPC. The patient was well-managed and had no post-operative complications or recurrence until day 180 of follow-up.
