Adrenals Glands


Smallest paired organ in suprarenal location in the abdomen.

Weighs ~4 grams each in the normal nonstressed adult.

Though CT is a better imaging modality, USG may be helpful depending on the operator experience, patient’s body habitus, and type of equipment.

In the neonatal period, normal adrenal gland can be visualized readily because of its relatively large size and little perirenal fat.

V/Y/Z shaped.

Long linear structure lying flat (Lying down sign in patients with renal agenesis).
