title: Ultrasonographic evaluation of adrenal glands in dogs with primary hypoadrenocorticism or mimicking diseases.
abstract: The adrenal glands of 30 dogs with primary adrenal insufficiency (hypoadrenocorticism) were measured ultrasonographically and compared with those of 14 healthy dogs and those of 10 dogs with diseases mimicking hypoadrenocorticism. Thickness and length of the adrenals were measured on abdominal ultrasonography and the results for each group were compared. Dogs with primary hypoadrenocorticism had significantly thinner adrenals compared with the other two groups, and their left adrenal glands were also significantly shorter than those of healthy dogs. Adrenal ultrasonography may be of diagnostic value in dogs with clinical signs suggestive of primary hypoadrenocorticism, as a left adrenal gland measuring less than 3.2 mm in thickness is strongly suggestive of the disease.
