Summary

Adrenocortical tumors were diagnosed in 5 adult spayed ferrets. Four ferrets had bilaterally symmetrical alopecia of the caudal femoral region, abdomen, and tail, and 1 had alopecia of the distal limbs and feet. All 5 ferrets had vulvar swelling. During abdominal ultrasonography, irregular masses, believed to involve the adrenal glands, were seen in all 5 ferrets. Unilateral adrenalectomy was performed successfully in each ferret by use of ventral midline celiotomy. On histologic examination of biopsy samples, 4 ferrets were found to have adrenocortical adenomas, and 1 ferret was found to have an adrenocortical adenocarcinoma. All clinical signs resolved after adrenalectomy, suggesting that the adrenocortical tumors had been secreting adrenocortical hormones.

Summary

Assays were validated for the measurement of urinary concentrations of cortisol and creatinine in domestic ferrets (Mustela putorius furo). Urinary concentrations of cortisol and creatinine and the calculated urinary cortisol:creatinine ratio (UCCR) values were determined for 29 clinically normal female ferrets, 22 clinically normal male ferrets, and 12 ferrets with adrenal gland tumors. The UCCR values for the 51 clinically normal ferrets ranged from 0.04 × 10-6 to 1.66 × 10-6, with a median value of 0.22 × 10-6. The UCCR values were significantly (P ≤ 0.01) higher in the 12 ferrets with adrenal tumors, with a range of 0.5 × 10-6 to 60.13 × 10-6 and a median of 5.98 × 10-6. We concluded that determination of UCCR values was useful in the diagnosis of hyperadrenocorticism associated with adrenal neoplasia in domestic ferrets.
