A 17-year-old neutered male DSH cat was presented to the emergency clinic with open-mouth breathing suspected to be secondary to stress/pain as the patient improved on analgesics. On a prior physical examination, an abdominal mass had been palpated.
A 17-year-old neutered male DSH cat was presented to the emergency clinic with open-mouth breathing suspected to be secondary to stress/pain as the patient improved on analgesics. On a prior physical examination, an abdominal mass had been palpated.
Deep right liver mass impinging upon the diaphragm and vena cava dorsally; the mass is likely not resectable. This is probably a cystadenoma, but adenocarcinoma is possible. A right perirenal cyst with a concurrent renal cortical cyst is noted in the right kidney. There is significant renal dystrophy of both kidneys, with pyelectasia or potential concurrent urinary tract infection.
The liver contained a macrocystic mass with heterogenous parenchymal changes that occupied the deep right liver with impingement upon the diaphragm and vena cava. The right kidney in this patient was surrounded by a large perirenal cyst formation that measured 8.44 cm. The kidney itself demonstrated a chronic interstitial nephrosis pattern with a cortical cyst and measured 5.4 cm. Post drainage the right kidney measured 5.1 cm with pyelectasia and loss of corticomedullary definition. The left kidney displayed moderate dystrophic changes with collapsed architecture, chronic interstitial nephrosis pattern, concurrent renal cyst, and measured 3.12 cm
Unfortunately, no further outcome was provided.
Along with the diagnostic sampling that was conducted via exploratory celiotomy, urine culture and sensitivity, broad-spectrum antibiotics and a 72-hour fluid therapy protocol was recommended in this patient due to the pyelectasia suggestive of possible chronic infection.
Abdominal mass – neoplasia, granuloma, abscess or cyst of internal organ, hydronephrosis.
Exploratory celiotomy with right perirenal cyst excision, renopexy and liver biopsy was performed, but no histological results are available at this time.
