ULTRASONOGRAPHIC DIAGNOSIS OF AN ADRENOCORTICAL CARCINOMA IN A DOG

The ultrasonographic findings in a nine-year-old female Drahthaar with an adrenocortical carcinoma of the left adrenal gland are described. Examination of the abdomen revealed a large, hypoechoic mass cranial t o the left kidney. Areas of calcification inside the mass and the late ral displacement of the caudal vena cava were assessed. The right adre nal gland was thinner and smaller than normal. Several target-like les ions were present in the hepatic parenchyma. A moderate amount of haem orrhagic abdominal fluid was also present. The ultrasonographic findin gs were consistent with this type of adrenal neoplasia which produces atrophy of the contralateral gland and frequently metastases to the li ver. The ultrasonographic diagnosis of adrenocortical carcinoma was co nfirmed by histopathological examination.
