Abstract

The aim of this study is to evaluate cervical ultrasonography as methods for diagnosis of hypothyroidism. 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.
