Abstract

This study evaluated ultrasonographically the liver of cats submitted to induced thyrotoxicosis by the technique of gray-level histogram with the objective of better evaluating the possible hepatic alterations decurring from the excess of the thyroid hormones. For that, there were used nine adult-young healthy cats, which received daily 150ìg/kg of sodic levotiroxin, for 60 days. The hepatic histogram has not demonstrated statistical differences in the 5% level of significance between the evaluated moments; however, the variations of the studied variables' values suggested an increasing of the heterogeneity and a decreasing of the echogenicity of the hepatic parenchyma when compared to the initial moment. The cytopathologic and histopathologic evaluations have shown of a clinical picture of thyrotoxic hepatitis in all the animals.
