Congenital cystic renal mass
Coco a 1 yr old female mixed breed dog was presented at PASHA wing with the history of abdominal distension. On physical examination abdomen was painful on palpation. Ultrasound imaging showed large cystic mass displacing abdominal organs. CT scan confirmed the diagnosis as cystic mass of renal origin involving the left kidney.
Renal cysts are more commonly encountered in cats than dogs. They appear both in tubular system of nephrons as well as sub-capsularly. Most of them are formed during organ genesis in embryonic period, while some others form over the due course of time due to various reasons.
Recommend line of treatment is nephrectomy provided contra-lateral kidney is functioning normally.
