Resumo
The sonographic evaluation of thyroid glands in veterinary medicine presents challenges due to the complexity of the anatomical region, professional experience and type of ultrasonography equipment. The technique is considered a versatile diagnostic method that is noninvasive and has a low cost indicated in different clinical situations. Thyroid carcinoma is a malignant tumor that is often invasive and frequently metastatic to regional lymph nodes and lungs. The prognostic indicators for survival after surgery include tumor size, histological type, mobility and presence or absence of metastasis. The objective of the present report is to demonstrate the importance of ultrasound as a complementary method in the evaluation of thyroid carcinoma in dogs. At the Dr. Halim Atique Veterinary Hospital, an eight-year-old male Pit Bull was examined due to a history of firm painless swelling, approximately six inches in diameter, in the ventral cervical region, for about two months. The sonogram showed a nodular area, with defined and regular margins, and heterogeneous hypoechoic parenchyma, with areas of cavitation and swelling of the thyroid. Histopathology of the nodule was consistent with carcinoma. After thyreoidectomy and hormone replacemet, the patient is in good clinical condition.
