Portuguese. O objetivo do presente estudo foi avaliar a ultra-sonografia das glândulas tireóides em animais com hipotireoidismo primário. Foram utilizados dez cães hipotireoideos, diagnosticados, através de anamnese, exame físico e exames laboratoriais, tais como dosagens séricas de T4 total, T4 livre, TSH, colesterol e triglicérides; e 10 cães eutireoideos A ultra-sonografia cervical revelou nítida redução do volume total da glândula tireóide em todos os animais hipotireoideos, estatisticamente significante (p<0,05), em comparação aos animais considerados eutireoideos, denotando, assim, a existência de atrofia glandular, secundária ao hipotireoidismo.

Twenty dogs were distributed in 2 groups: 10 dogs with hypothyroidism, and 10 healthy dogs as a control group. All dogs were submitted to ultrasonographic examination in the cervical area. To confirm hypothyroidism diagnosis, total T4, free T4 and TSH hormones samples were obtained and, also, cholestherol and triglycerides. Hypothyroid animals submitted to cervical ultrasonography showed marked reduction in the total volume of the thyroid gland, with statistical significance (p<0,05), in comparison to normal dogs. This alteration demonstrated the gland atrophy secondary to hypothyroidism.
