AEMV-Lafeber Case Report: Hyperthyroidism Treated with Radiation Therapy (I-131) in Two Guinea Pigs
Two guinea pigs suspected of having hyperthyroidism based on weight loss, presence of a cervical mass, and elevated total thyroxine (TT4) levels were confirmed to have active thyroid masses via scintigraphy with Technetium-99 and treated with radioactive iodine therapy (I¹³¹). Both patients responded initially with weight gain and a decrease in the TT4. The purpose of this case series is to describe the use of scintigraphy to aid in confirming a diagnosis of hyperthyroidism, as well as to show the benefits and effectiveness of using radioactive iodine therapy (I¹³¹) to treat hyperthyroidism in guinea pigs in order to provide the best treatment protocol.
