The serum thyroxin (TJ, thyrotropin (thyroid stimulating hormone, TSH) concentrations of thirty one dogs (16 females, 15 males) and ten cats (5 females and 5 males) were measured parallel with technetium-pertechnetate scintigraphy. Fourteen (45%) dog patients suffer from malignant and seventeen (55%) patients from benign thyroid transformations. Its proportion in cats was 4 (40%) and 6 (60%). Serum TSH concentrations of eleven dog patients was lower and TSH of ten dog patients was higher than physiological level. Serum T4 concentrations did not differ statistically in malignant and benign tumours and in different species. There was no statistical difference in pertechnetate-uptake between malignant and benign tumours. There was no correlation between T4 and pertechnetate-uptake ranging on basis of species or histopathology. Extremely high serum T4 concentrations were measured in cases of multinodular hyperplasia, nodular atrophy and thyroiditis. In contrast, pertechnetate-uptake was the highest in cases of compact cell carcinomas, follicular adenocarcinoma and follicular compact cell carcinoma. Standard deviation of serum TSH concentrations was the highest in case of follicular adenomas.
