Archive Case #118: Feline Hyperaldosteronism

Clinical Clues

1. An older cat is examined for progressive weakness and unusual posture.
2. The owner also reports episodes of visual disturbance and increased drinking.
3. On examination the neck is ventroflexed and systemic blood pressure is high.
4. Bloodwork reveals marked hypokalaemia.
5. Imaging identifies an adrenal mass.
6. Feline hyperaldosteronism causes excess aldosterone, hypertension, and potassium depletion.

Diagnosis

Feline Hyperaldosteronism

This case is most consistent with Feline Hyperaldosteronism because the cat has hypertension, hypokalaemia, cervical ventroflexion, and an adrenal lesion. The most important clues are the potassium depletion and blood pressure changes, which make a primary neurologic disease less likely.
