Adrenocortical Disease in Ferrets

Key Points

  • Hyperadrenocorticism is a common condition of domestic ferrets, affecting middle-aged to older ferrets.
  • The most common clinical sign of hyperadrenocorticism in ferrets is progressive alopecia of the tail, tail base and trunk.
  • Vulvar enlargement may be seen in  spayed females with hyperadrenocorticism.
  • Male ferrets may present with a history of stranguria or urinary tract obstruction due to prostatomegaly.
  • Experienced ultrasonographers can detect adrenomegaly (width > 3-3.5 mm) or abnormal adrenal architecture.
  • Hormone panels are also available. Most affected ferrets have elevated levels of estradiol, androstenedione, and/or 17α-hydroxyprogesterone.
  • Medical therapy using deslorelin implants, though not curative, is recommended. Ferrets may remain asymptomatic for a median of 1-1.5 years.
  • Adrenalectomy may be indicated in case non-responsiveness to medical treatment, although adrenalectomy of the right adrenal gland is difficult.

Hyperadrenocorticism is a common and complex clinical condition in the pet ferret. This disease occurs most frequently in ferrets three years or older but has been reported in animals as young as one year of age. Presumptive diagnosis of adrenal disease in the ferret is based on history, clinical signs, imaging diagnostics, and steroid hormone analysis. Medical therapy using deslorelin implants, though not curative, is recommended. Ferrets may remain asymptomatic for a median of 1-1.5 years. Adrenalectomy may be indicated in case non-responsiveness to medical treatment, although adrenalectomy of the right adrenal gland is difficult . . .
