| Abstract: | A 3-year-old castrated male domestic ferret was evaluated for abdominal distention. Survey lateral and dorsoventral abdominal radiographs were made. There were two soft tissue radiopacities consistent with grossly enlarged kidneys displacing small bowel and colon cranially, ventrally and caudally. Abdominal ultrasound was performed and revealed bilateral perinephric pseudocysts and polycystic kidneys. The perinephric pseudocysts were found to be dilated renal capsules on exploratory surgery and were drained. On follow up examinations, the pseudocysts were drained by ultrasound-guided paracentesis. The perinephric cyst fluid was distinguished from urine by measuring creatinine concentration and plans were made to resect the renal capsules due to rapid re-accumulation of pseudocyst fluid. The ferret's condition deteriorated and euthanasia was performed. Post-mortem examination was declined by the owner. Perinephric pseudocysts are rare and this is the first published report in a ferret. Ultrasound examination is the most rapid, accurate and non-invasive method for diagnosis of perinephric pseudocysts. |
