Ultrasonographic evaluation of the size of the adrenal glands of 24 diseased cats without endocrinopathies.

The ultrasonographic measurements of the adrenal glands of 24 diseased cats without a clinically or laboratory identifiable endocrinopathy were evaluated retrospectively. The mean (sd) thickness of the left adrenal glands was 3.8 (0.8) mm and their mean length was 11.3 (2.8) mm; the thickness of the right glands was 4.5 (1.0) mm and their length was 9.8 (2.4) mm. The products of thickness and length were 43.9 (20.2) mm(2) for the left gland and 45.7 (19.7) mm(2) for the right gland. There were no significant correlations between the bodyweight, body surface area or body condition scores of the cats and the thickness, length or the product of thickness and length of either gland.
