Abstract

Ultrasound-guided percutaneous ethanol injection (PEI) was evaluated in 4 cats as a treatment for a unilateral hyperplastic thyroid nodule. Cats were anesthetized with a short-acting agent, and a 27-gauge needle was directed into the thyroid nodule with guidance by ultrasound. A precalculated dose of 96% ethanol solution was injected, and diffusion of the fluid throughout the gland was readily apparent. Serum thyroxine (T₄) and free T₄ concentrations decreased to or below reference ranges in all cats within 48 hours, and remained so during the 12-month study period. All cats have been assessed as clinically normal and have had no clinical signs of hyperthyroidism since PEI. No severe adverse effects were observed. Results of follow-up pertechnetate scans were normal in 2 cats and abnormal in 2 cats. We concluded that PEI is likely a safe and efficacious treatment for hyperthyroidism caused by a unilateral hyperplastic nodule in cats.
