Plain-English summary

A 5-year-old guinea pig was brought in for an ultrasound because it was losing hair, seemed lethargic, and was overweight. The ultrasound revealed a tumor on the left adrenal gland and a stone blocking the left ureter, which was causing kidney swelling. During surgery to remove the stone and the tumor, the guinea pig unfortunately lost too much blood and died. The tumor was identified as an adenoma, and the stone was made of calcium carbonate.

Abstract

A 5‐year‐old guinea pig was presented to the University of Berne Small Animal Radiology Department for an ultrasound examination of the abdomen to confirm a suspected diagnosis of Cushing's syndrome. The patient had bilateral alopecia, was apathic and obese. Ultrasonographically, a tumor of the left adrenal gland, obstruction of the left ureter by an ureterolith, as well as hydronephrosis of the left kidney were detected. During surgery to relieve the ureteral obstruction the adrenal gland tumor was removed. The guinea pig died post‐operatively due to blood loss. The left adrenal gland tumor was found histopathologically to be an adenoma and the right adrenal gland also had multiple small adenomas, but grossly appeared normal. The ureterolith was analyzed and found by x‐ray diffraction to consist of calcium carbonate.
