  • A 13-year-old neutered female Maltese was referred to Veterinary Medical Teaching Hospital of Seoul National University with 8-month-history of gradually enlarging retrobulbar mass in the right eye. On the ophthalmic examinations, exophthalmos, exposure keratitis, and cataract were observed, and menace response was absent in the eye. The fellow eye was normal except for nuclear sclerosis. On the ocular ultrasonographic evaluation, a mass was identified in retrobulbar and periocular region in the right eye. Exenteration was performed in order to remove the mass. Histopathologic evaluation revealed that most part of the mass was composed of epithelial-like neoplastic cells. Invasion into adipose cells and osseous metaplasia around the mass were also confirmed. Based on the radiologic and histopathologic examination, the mass in the right eye was diagnosed as primary retrobulbar meningioma. Eleven months after the surgery, recurrence was not observed.

  • 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.
